Synthetic description of the activity and expected research outcome: Point defects in wide band gap semiconductor like diamond and silicon carbide have attracted attention for quantum technology application. The optically active defects, often referred as color centers, are appealing candidates for the solid-state integration of stable single-photon sources for quantum photonics and computing. Furthermore, new sensing opportunities are possible, enabling measurements at the nanoscale, potentially including biological samples, and of weak signals like in advanced magnetometry. The FBK facilities are involved in research projects on diamond and SiC where the deterministic creation of such centers is pursued using state-of-art instrumentation like a multi-species focused ion beam system (FIB) and semiconductor processing techniques, including the nanometric patterning offered by electron beam lithography. The installed FIB allows implantation of Si, Ge and Au at depths well below 50 nm, with lateral resolution of 50-100 nm, and with fluences down to few ions implanted, enabling the deterministic creation and localization of color centers [1].
The proposed research work aims to the creation of color centers in one of these materials, their characterization and their integration in view of advanced quantum sensing applications. The research activity will be integrated in the European projects where our facilities are involved and in collaboration with external partners.

Quantum System Identification by Hamiltonian Learning
Research group link https://hauke-group.physics.unitn.it/
Contacts: Prof. Philipp Hauke (UniTN) mailto:philipp.hauke@unitn.it Dr. Sebastian Schmitt (HRI)
Synthetic description of the activity and expected research outcome The characterization and prediction of material properties is one of the most promising application areas for quantum computing and simulation, with potential applications ranging from the design of new batteries to low-loss conductors and efficient solar cells. However, a central problem for the simulation of specific materials is the need to identify the relevant quantum degrees of freedom that need to be included in the simulation. A recent approach to this problem is given by Hamiltonian Learning, in which one aims to determine the effective description, i.e. the form of the Hamiltonian, in the relevant regime from a set of measurement data.
The PhD project will explore the limitations and benefits of Hamiltonian Learning [1,2] for the description and discovery of novel quantum materials. Target questions will include how to impose continuous control with unknown or only partially known structure of the Hamiltonian, or how to efficiently impose Hamiltonian learning using technologies like generative adversarial neural networks [3], tensor networks [4], or neural differential equations [5]. We will also analyze in how far universality of quantum many-body systems in and out of equilibrium [6] permits to circumvent fine tuning. A further aim is to implement the developed schemes on quantum hardware. To obtain high-quality results, we will implement state-of-art error-mitigation techniques [7]. While the impact of hardware noise on the learning process is insufficiently well investigated, the recent trend to use machine learning for error mitigation [8,9] opens new opportunities. A clear route should be illustrated of how to scale the proposed learning system to the necessary system sizes to describe realistic materials, leveraging recent approaches of partitioning, parallelization, and hybrid quantum-classical schemes [10-12]. Thanks to strong ties with leading experimental groups, we aim to test the developed frameworks in theory-experiment collaborations on cold atoms, trapped ions, or superconducting qubits. The final target of the research activities will be the development of a practical Hamiltonian learning framework that can be used to understand and predict properties of realistic materials [13].
The research will be mainly carried out at University of Trento, Italy, with the possibility of extended stays at Honda Research Institute Europe in Offenbach, Germany. International cooperation is foreseen within a network of collaboration partners, including leading theoretical and experimental teams.

Synthetic description of the activity and expected research outcome: FLASH radiotherapy consists in a new and promising approach for cancer treatment, based on the experimental observation that extremely reduced irradiation time (i.e. order of 100 ms) results in sparing of normal tissue toxicity and same effectiveness on tumor cells compared to conventional irradiation, which takes place on a longer time scale (i.e. tens of seconds to a few minutes). The radiobiological mechanisms behind the FLASH effect are not fully understood, and extensive research is ongoing also aiming at the clinical translation of this innovative approach. Thinking of clinical applications, protons currently appear as the ideal candidate to set up treatments at ultra-high dose rate, thus exploiting the FLASH effect. However, there is the need to implement robust treatment, able to exploit the full potential of the protons’ depth-dose curve (i.e. the Bragg peak). This project will be dedicated to the study of 3D range modulators that, combined with the delivery of a single layer of high energy protons, would result in conformal treatments, exploiting at the same time the advantages of the FLASH effect. The research project will include both optimization and implementation of 3D RM geometries into dedicated software, including Monte Carlo codes, and experimental validation of the proposed approach. The PhD student will also be involved in the characterization of the newly realized experimental FLASH beamline in Trento.

Contacts: Francesco Giuseppe Cordoni (francesco.cordoni@unitn.it), Emanuele Scifoni (scifoni@infn.it)
Synthetic description of the activity and expected research outcome:
Over the past decades, radiotherapy (RT) has demonstrated remarkable efficacy in curing cancer. The rationale for using hadrons in cancer treatment is based on their unique energy loss mechanisms, which offer significant biological benefits over photons, including enhanced tumor control and reduced damage to healthy tissues.
Despite the potential superiority of hadrons in theory, additional research is crucial to fully incorporate this treatment modality into clinical practice. One of the primary obstacles to the widespread use of hadrons is the difficulty of accurately estimating the biological effect caused by the specific radiation. Over the years, several mechanism-based mathematical models have been developed to understand and predict the effect of a given radiation on biological tissue.
Further, more recently, modern Machine and Deep Learning (MDL) algorithms have been proposed to tackle the same problem. Despite the collective efforts of the scientific community, there is currently no universally accepted superior model for predicting the biological effect of radiation. The absence of a reliable and all-encompassing model poses a significant obstacle to fully leveraging particle therapy, including the use of heavier ions like oxygen to treat radio-resistant tumors, and the adoption of multi-ion therapy, which is now technically feasible.
The project aims to develop a hybrid model to predict the biological effect of radiation, merging standard mathematical approaches with modern artificial intelligence-based models. The resulting model will have the interpretability and physically grounded foundation of mathematical models and the extreme flexibility and accuracy of modern MDL models. The model will be based on the advanced physical description of the radiation field, using microdosimetry and/or nanodosimetry, and will explore the relative importance of different radiation quality descriptors. An optional experimental verification part could be added upon the availability of the facility.
The project will be carried out in the BiMeR team, between TIFPA-INFN, UniTN, and the APSS proton therapy center.

Topic: Laboratory molecular astrophysics: understanding the formation and destruction mechanisms of molecules in the interstellar medium and planetary atmospheres
Research group link: https://molecular.physics.unitn.it/
Contacts: Prof. Daniela Ascenzi (daniela.ascenzi@unitn.it)
Synthetic description of the activity and expected research outcome: Over 300 molecules have been detected in the interstellar and circumstellar regions of our galaxy (see https://cdms.astro.uni-koeln.de/classic/molecules and http://www.astrochymist.org/astrochymist_ism.html). Astronomers use molecules as a tool to infer information about the structure, dynamics and evolution of astronomical objects (e.g. molecular clouds, protostars, planetary atmospheres). For instance, the chemical composition of Solar-like planetary-forming systems can be used to unveil the history of our Solar System. Astrochemical models have been developed to compute the evolution of the physical parameters and chemical composition of a mixture of gas and dust under astrophysical conditions, and such models are the key to relate astronomical observations with the structure of the observed objects. The key elements in astrochemical models are the kinetic parameters of the chemical reaction networks at play. The PhD project aims at measuring such kinetic parameters for gas phase processes involving charged species and leading either to the destruction or to the formation of interstellar molecules. Experiments will make use of a tandem guided ion beam mass spectrometer to measure absolute cross sections and product branching ratios as a function of collision energy for a variety of ion-neutral reaction systems (including specific isomers) in the gas phase under single collision conditions.

Growing tensions among different probes (such as the H₀ and S₈ tensions) are hinting at the breakdown of the current concordance model, and we will study the possibility of such tensions shedding light on the microphysical nature of DM and DE, constructing models which may solve these tensions.
We will study cross-correlations between different probes, including gravitational waves, as a way to shed light on DM and DE, and test gravity. Based on the student's interests, this project offers significant flexibility in terms of focusing more on theoretical or data analysis aspects, or extending the research scope. Throughout the project, the student will have the possibility of collaborating with a wide network of researchers worldwide (see https://www.sunnyvagnozzi.com/en/publications).
Ideal candidate (skills and competencies): The ideal candidate has a strong background in cosmology. Advanced knowledge of General Relativity, QFT, and particle physics is also very welcome. Depending on the student’s inclination, this project is very flexible and can require either or both analytical and numerical skills, in varying proportions. For more computationally-oriented students, excellent computational skills, ideally the ability to program in Python and at least a low-level language (e.g. C/C++/Fortran), are highly recommended. Familiarity with cosmological codes such as CAMB, CLASS, CosmoMC, MontePython, and Cobaya, is welcome. Some experience with statistics is an additional asset.
More generally, we are looking for a passionate, independent, and self-driven student with strong interests in cosmology and tests of fundamental physics using observations collected around the Universe, and a strong work ethic. The student must be able to work independently and as part of a team. For the latter, good organization and communication skills are essential.

Synthetic description of the activity and expected research outcome: Scale-invariant gravity is a well-motivated model of fundamental physics. It essentially claims that, in a very high energy regime, gravity becomes an interaction that is not modulated by any fundamental scale (the Newton constant, for instance, becomes the value of a field that changes in time and space). Such a theory has been deeply investigated in our group in the context of cosmic inflation and in the context of black hole physics. So far, these investigations were carried out in the classical regime and our aim is to explore the quantum regime of the theory and its phenomenological traces in cosmology and black hole physics. The thesis project aims to tackle these challenging questions and to produce theoretical and observational constraint on the parameter space of the theory. The project will be carried out with a wide network of collaborators (see website) with possibilities of visiting other groups.

Cosmological coupling of black holes (Rinaldi)
Topic: Cosmological coupling of black holes
Research group link:https://sites.google.com/unitn.it/gravity-and-cosmology/home
Contacts: M. Rinaldi massimiliano.rinaldi@unitn.it
Synthetic description of the activity and expected research outcome: By the terms cosmological coupling we indicate a phenomenon for which the mass of black holes grows with the expansion of the Universe. In some models, this growth is even responsible for the dark energy content of the Universe, provided the usual Schwarzschild or Kerr metric is replaced by a suitable one. The possibility of a cosmological coupling is an old problem posed by McVittie and other authors on a pure mathematical ground. But it recently came back to being popular thanks to some evidence obtained by observing a certain class of elliptic galaxies. The aim of the project is to explore in depth the mathematical and physical consistency of this idea and to root it in some fundamental theory of gravity, classical or quantum, with an eye on possible phenomenological implications. For more details, please refer to: https://arxiv.org/abs/2407.14549; https://arxiv.org/abs/2409.01801; https://arxiv.org/abs/2302.07878 and references therein.

Quantum simulation of strongly-correlated quantum systems (Hauke)

Research group link: https://hauke-group.physics.unitn.it/
Contacts: Prof. Philipp Hauke (University of Trento)
Synthetic description of the activity and expected research outcome: Quantum many-body systems host a manifold of intriguing emerging phenomena, which appear due to strong correlations and the spread of quantum information between many particles. Today, many fundamental questions of strongly-correlated systems, in and out of equilibrium, remain unsolved due to the generic hardness to solve them on classical computers. However, the pristine control over quantum systems such as ultracold atoms or trapped ions has now handed us an alternative way, that of solving quantum many-body systems “by experiment”. In this approach, one reproduces the microscopic equations of a quantum system in a device that is itself governed by quantum mechanics. First envisioned by Feynman in 1982, this is now becoming a reality under the name of quantum simulation. The aim of this PhD project is to push the boundaries of quantum simulation. Prime targets will be AMO implementations of systems with disorder, long-range interactions, or gauge symmetries, in order to probe emerging phenomena such as topological states of matter, confinement, chaotic dynamics, scrambling of quantum information, and thermalization of closed quantum systems. The project covers a wide range of possible work opportunities, from developing state-of-art computational and analytical tools for probing many-body properties all the way to proposing and benchmarking experimental implementations.
Ideal candidate (skills and competencies): The ideal candidate has a strong background in quantum mechanics and quantum many-body physics, in particular, e.g., in atomic physics, quantum optics, quantum information, quantum computing, field theories, and condensed matter. Strong analytical and computational skills are required. They should have a high interest in cross-disciplinary research questions and in collaborating with leading theorists and experimentalists across the globe.

Synthetic description of the activity and expected research outcome :
Measurements lie at the heart of quantum mechanics — not just as passive observations, but as active agents that alter the course of quantum dynamics. A single measurement can collapse the wave function or drastically alter a system’s trajectory through Hilbert space. This PhD project dives deep into the role of measurements in quantum many-body systems, exploring how observation itself can drive fascinating and counterintuitive phenomena. A central focus will be on how measurements induce entanglement phase transitions — abrupt changes in the internal correlations of quantum systems triggered by the very act of observation. We'll also explore how continuous monitoring alters quantum dynamics, carving out forbidden regions in Hilbert space — a striking manifestation of the Quantum Zeno Effect, where watching too frequently can freeze motion. Beyond the fundamental interest in understanding nonequilibrium quantum dynamics, these insights have real-world impact. As quantum simulation and computation scale up, error correction becomes critical. In this project, we aim to design smart, tailored measurements that leverage the Zeno effect to actively suppress errors in simulations of interacting lattice models. This project offers the opportunity to work at the intersection of nonequilibrium quantum dynamics, statistical mechanics, and their applications to emerging quantum technologies. During the PhD project, the student will have the possibility of collaborating with an extended network of researchers worldwide.

When a quantum system interacts with its environment, its dynamics is driven by the dynamic balance between coherent evolution and dissipative processes. In this project, we explore the rich collective behavior that emerges in quantum many-body systems coupled to an external bath. Our focus will be on understanding how correlated dissipation can give rise to novel thermodynamic phases, and how the interplay between interactions and openness can stabilize unconventional stationary states far from equilibrium. The PhD candidate will investigate how engineered dissipation and external driving can be harnessed to control and shape the nonequilibrium dynamics of these systems. Beyond its fundamental relevance, this research provides practical insights: studying open quantum systems equips students with powerful tools to model errors, decoherence, and imperfections, key challenges in the development of next-generation quantum technologies.

Synthetic description of the activity and expected research outcome: Over the past 20 years, ultra-cold gases have emerged as an ideal platform to study fundamental aspects of many-body systems, including Bose-Einstein condensation, Fermi superfluidity, out-of-equilibrium dynamics, and open quantum systems. At the Pitaevskii BEC Center, we have contributed to several areas of cold-atom research. We are currently seeking PhD candidates to work on two main topics:
- Rotonised and Supersolid phase of Bose-Einstein condensates
The supersolid state of matter was experimentally realized in ultra-cold gas systems five years ago. Since then, we have been studying its remarkable properties. This PhD project focuses on extending that investigation, particularly exploring the dynamics of wave packets in non-uniform systems, the behavior of quantized vortices in three-dimensional supersolids, and supersolid mixtures. The theoretical framework includes the Gross-Pitaevskii equation and its generalizations, as well as hydrodynamic theory.
Due to the novelty of the system, many of its properties remain to be fully understood. The project is expected to advance our theoretical knowledge of supersolids and cold gases in general, with the potential to inspire new experimental studies, in close collaboration with leading laboratories across Europe.
- Quantum Mixture and Magnetic Superfluids
This project will be developed in close synergy with experimental colleagues in Trento. It concerns a recently realized and unique system: the magnetic superfluid. Using a density functional approach, the quantum Gutzwiller method, and tensor network techniques, we aim to study out-of-equilibrium dynamics, quantum fluctuations, and the realization of beyond mean-field states with strong two-body entanglement.
The expected outcome includes theoretical predictions that may guide new experiments and reveal quantum effects and critical behavior in extended atomic samples.
Ideal candidate (skills and competencies): Applicants should hold an MSc in Physics and demonstrate strong proficiency in English. A collaborative attitude, both within national and international research contexts, is essential. Prior experience with scientific numerical simulations is highly desirable.
Electron-Phonon Interaction in Strongly Correlated Systems (Cudazzo)
Topic: Electron-phonon interaction in strongly correlated systems
Research group link: https://mattheory.physics.unitn.it/
Contacts: pierluigi.cudazzo@unitn.it
Synthetic description of the activity and expected research outcome: The interaction between electron and phonon is responsible for many key phenomena such as superconductivity, electronic transport, charge density waves, and structural distortions.
The state of the art in describing this interaction is density functional perturbation theory with semilocal functionals. However, this theory breaks down when the interaction between the electrons is strong — in strongly correlated systems.
In this PhD thesis, we plan to use advanced many-body perturbation theories to develop theoretical and numerical approaches beyond the current state-of-the-art in electron-phonon scattering. These methods will be applied to strongly correlated systems such as high-Tc superconductors, low-dimensional correlated systems, and other materials of high technological relevance.
Ideal candidate (skills and competencies): Passion and motivation for research, curiosity. Strong background in quantum mechanics and in theoretical solid-state physics.
Excited States of Matter and Their Out-of-Equilibrium Dynamics (Cudazzo)
Topic: Excited states of matter and their out-of-equilibrium dynamics
Research group link: https://mattheory.physics.unitn.it/
Contacts: pierluigi.cudazzo@unitn.it
Synthetic description of the activity and expected research outcome: Among the emerging fields of condensed matter physics is "excitonics". It aims at the realization of devices operating with excitons instead of electrons, with great potential to achieve breakthroughs in optoelectronics.
An exciton is an excited state of matter consisting of a bound electron–hole pair generated by photon absorption. It represents the crucial intermediate for energy transduction and nanoscale light control. To achieve this ambitious goal, the exciton must be controlled and manipulated during its formation.
The aim of this proposal is the development of theoretical tools for the description of exciton dynamics. In particular, the problem will be addressed using a rate equation for excitons, where the coupling with other degrees of freedom (such as lattice vibrations) responsible for exciton thermalization is taken into account through an effective exciton potential, to be suitably approximated.
This approach will allow us to investigate exciton dynamics and simulate basic out-of-equilibrium spectroscopies, such as transient absorption and time-resolved photoluminescence.
The basic questions we aim to answer are:
What are the physical mechanisms governing exciton relaxation and decoherence?
How are they related to the electronic structure of materials?
How can materials be engineered to tune exciton lifetime, decoherence length, and to control exciton flux?
This proposal will impact chemistry, physics, energy, and materials engineering. On one hand, the developed theoretical tools will give access to new physical phenomena that have never been investigated using full ab-initio methods. On the other hand, they will allow the design of new materials and compounds for excitonic technologies.
Ideal candidate (skills and competencies): Basic knowledge of condensed matter physics and many-body Green’s function theory. Programming skills (Fortran, Python, Unix) are also required.

Integrated squeezed vacuum source for measurements beyond the quantum limit (Leonardi)
Topic: Integrated squeezed vacuum source for measurements beyond the quantum limit
Research group link: https://www.physics.unitn.it/854/gravitazione-sperimentale
Contacts: Dr. Matteo Leonardi (matteo.leonardi.1@unitn.it)
Synthetic description of the activity and expected research outcome: Almost ten years after the first direct detection of gravitational waves by the LIGO-Virgo collaboration, over 100 gravitational wave events from stellar mergers have been observed. Despite their remarkable sensitivity, current gravitational wave detectors remain limited by noise. As a result, signals must be observed simultaneously in multiple detectors to be confirmed.
One of the dominant sources of noise is the quantum nature of light itself. In particular, quantum vacuum fluctuations of the electromagnetic field pose a major challenge for advancing gravitational wave astronomy. A solution to mitigate this quantum noise is the use of squeezed states of light — specially engineered quantum states that redistribute noise between amplitude and phase quadratures via nonlinear optical processes. This technique has already been implemented in the latest detector runs.
However, the production of squeezed light is technically demanding and limits its widespread adoption. The proposed PhD project aims to develop an integrated squeezed light source, making this powerful quantum enhancement technique more broadly accessible. While gravitational wave detection remains a primary target, the system may also benefit other quantum technologies, including quantum computing and quantum cryptography.
Ideal candidate (skills and competencies): The ideal candidate possesses strong critical thinking and teamwork skills. Prior experience in optics is highly desirable, as is familiarity with simulation techniques and finite element modeling software.

Synthetic description of the activity and expected research outcome: Structural glasses are considered prototypical out-of-equilibrium materials. Their low-temperature thermal properties are strongly influenced by both structural disorder and localized "defects," often modeled as two-level systems whose microscopic nature remains elusive [1]. These characteristics give rise to complex atomic dynamics, including tunneling, thermally activated relaxations, and phonon-like vibrations [2].
Recent numerical simulations have identified quasi-localized vibrational modes in addition to extended phonon-like excitations [3]. However, experimental validation of these findings remains extremely challenging. This project aims to probe low-frequency vibrational modes and sound propagation in structural glasses in previously unexplored frequency regimes, leveraging recent advances in experimental techniques.
We will employ next-generation synchrotron sources (e.g., the upgraded ESRF in Grenoble) and free electron lasers, in addition to performing complementary light spectroscopy in Trento. The study will focus on a range of amorphous materials prepared using different protocols, in both bulk and thin-film forms.
Thin films of amorphous materials are especially relevant for gravitational wave interferometers like Advanced LIGO and Advanced Virgo, where their vibrational properties contribute to coating thermal noise — currently the dominant limitation to detector sensitivity in the most critical frequency range. Understanding these phenomena is essential for the design of third-generation gravitational wave detectors.

Understanding and mitigating these effects is crucial for the effective application of squeezed light in high-precision interferometry.

Overcoming the actual constrains of WOC requires designing novel catalysts which are both scalable, efficient and robust enough to operate on wastewaters. Promising candidates based on transition metals will be designed following band-engineering principles and with optimized morphologies at the nanoscale, implemented and tested. (2) Coupling concentrated sunlight to photoactive materials. The development of low-cost, small-scale and robust solar concentrators to provide low-to-moderate concentration factors (2-100) would open the way to PEC yield enhancement by increasing photon density, especially in the highly efficient near-UV range where natural light is lacking. Materials and equipments designed for this goal will be implemented by the PhD student.

Synthetic description of the activity and expected research outcome: Vitrimers constitute a recent class of materials currently representing a brand-new frontier in the field of advanced polymers. Their unique performances derive from the presence of covalent bonds, which exhibit reversible behavior under specific stimuli or environmental conditions. Unlike traditional thermosetting polymers, this reactivity grants vitrimers properties such as recyclability, self-healing, and re-processability—opening up new possibilities in sustainable material science. While current research focuses on developing new reversible systems and understanding structure–kinetics relationships, the next challenge is creating high-performance vitrimers entirely from biobased sources. Among the promising candidates, lignin—a by-product of the pulp and paper industry—offers high thermal stability, reactive functional groups, and broad availability. However, its variability in structure, molecular weight, and functionality presents significant challenges.
This PhD project aims to develop the next generation of reliable vitrimeric bio-materials by valorizing lignin from agricultural and forestry residues and tailoring material properties through precise control of lignin structure and reactivity.

Synthetic description of the activity and expected research outcome: Structural glasses are considered prototypical out-of-equilibrium materials. Their low-temperature thermal properties are strongly influenced by both structural disorder and localized "defects," often modeled as two-level systems whose microscopic nature remains elusive [1]. These characteristics give rise to complex atomic dynamics, including tunneling, thermally activated relaxations, and phonon-like vibrations [2].
Recent numerical simulations have identified quasi-localized vibrational modes in addition to extended phonon-like excitations [3]. However, experimental validation of these findings remains extremely challenging. This project aims to probe low-frequency vibrational modes and sound propagation in structural glasses in previously unexplored frequency regimes, leveraging recent advances in experimental techniques.
We will employ next-generation synchrotron sources (e.g., the upgraded ESRF in Grenoble) and free electron lasers, in addition to performing complementary light spectroscopy in Trento. The study will focus on a range of amorphous materials prepared using different protocols, in both bulk and thin-film forms.
Thin films of amorphous materials are especially relevant for gravitational wave interferometers like Advanced LIGO and Advanced Virgo, where their vibrational properties contribute to coating thermal noise — currently the dominant limitation to detector sensitivity in the most critical frequency range. Understanding these phenomena is essential for the design of third-generation gravitational wave detectors.
