The workshop is dedicated to study superfluid systems in nonequilibrium conditions. In the case of atomic nuclei, two processes depend crucially on superfluidity: induced nuclear fission and low-energy nuclear collisions involving heavy nuclei. In the case of neutron stars, superfluidity is at the heart of the so-called `glitches’ observed in pulsars, but also plays a crucial role in determining transport coefficients that can influence the cooling of the star and its gravitational wave emission. To model these phenomena, it is crucial to understand dissipative channels related to superflow, the dynamics of vortices, and the decay mechanism of a quantum turbulent state. On the other hand, thanks to advances in experimental techniques in the field of ultracold gases and helium liquids, we can investigate nonequilibrium phenomena in these superfluids and use both experimental and theoretical achievements in these fields to understand the most intriguing questions related to nonequilibrium superfluidity

In recent years, quantum technologies have garnered significant attention due to their promising applications, including quantum computation, cryptography, simulation of quantum many-body systems, and hybrid quantum-classical algorithms. As this field rapidly expands into specialized research areas, the Quantum Science Generation Workshop 2025 its third edition - aims to provide a comprehensive - and up-to-date overview of the most active research-areas within this field. The workshop will cover: (i) optical and condensed matter platforms for quantum computing; (ii) quantum simulation of problems of interest for condensed matter, nuclear, high-energy, or gravitational physics; and (iii) hybrid quantum algorithms for optimization problems. Targeted at young researchers at the PhD and PostDoc levels, the workshop seeks to foster discussion and collaboration across different quantum science disciplines, promoting new insights and advancing the field.

Lepton flavour change is observed in neutrino oscillations, but not yet in contact interactions among charged leptons – despite decades of active searching and a plethora of models. However, this could change soon, as a huge leap in experimental reach is promised by upcoming searches for μ → e conversion in nuclei. The workshop aims to bring together lepton, χPT/nucleon and nuclear theorists, in order to improve the multi-scale theoretical rate calculations, using state of the art mean-field or shell-model approaches, to the accuracy required by upcoming experiments. Also, in collaboration with experimentalists, we aim to explore feasible and complementary nuclear targets that could best identify the lepton flavour changing interactions.

The "mechanical properties" of hadrons have emerged as a new field of study in strong interaction physics. They refer to the hadronic matrix elements of the QCD energy-momentum tensor and related operators, which measure physical quantities carried by the quark and gluon fields inside hadrons, such as the momentum, angular momentum, and forces. These structures are studied theoretically using lattice QCD and effective theories, and measured experimentally through the connection with the partonic structure measured in high-energy scattering processes (generalized parton distributions). They can be interpreted in terms of classical concepts like a spatial distribution of matter, motion or forces, and open new possibilities for visualization and communication with other fields of science. The workshop will review the status of the field and assess the prospects for further developments in theory and experiment (JLab 12 GeV, EIC, hadron beam facilities).

Chiral anomalies lead to new transport phenomena such as the chiral magnetic and the chiral vortical effects. Due to the universality of anomalies these effects play an important role in many different areas ranging from the physics of heavy ion collisions to condensed matter systems such as Weyl- and Dirac metals. From the very beginning the theory of anomaly induced transport has received important inputs from holography (the “gauge/gravity” duality). In particular in view of the ongoing search for anomaly induced effects in heavy ion collisions it is necessary to deepen our theoretical understanding, develop new models and arrive at quantitative predictions. In addition, transport phenomena associated with spin and rotation are being investigated in heavy ion collisions. Holography is a very powerful tool that holds the promise to be able to successfully address all these issues. The workshop shall gather leading experts to discuss the status quo and foster new ideas and collaborations.

Lattice QCD calculations have reached per-mille-level precision for certain experimentally measurable quantities. Often, the limiting systematic uncertainty of such computations comes from determination of the lattice scale, converting the lattice results to physical units. A number of lattice collaborations carried out determinations of theoretical scales (e.g., a popular choice is the gradient flow scale) that are in slight tension. Lattice scale determination with fully accounted systematic uncertainties is not a purely theoretical question as it influences, for instance, the computation of the hadronic contribution to the anomalous magnetic moment of the muon and the determination of the CKM matrix elements. Thus, the precision of the lattice scale plays a direct role in confirming the Standard Model or differentiating new physics beyond the Standard Model

The workshop aims to examine current state and recent advances in nuclear astrophysics and identify crucial reactions that require assessment of information relevant to the field using stable and Radioactive Ion Beam (RIB) facilities. The workshop will bring together experimentalists and theoreticians studying nuclear reactions, along with physicists engaged in stellar and stellar-explosion modeling as well as in astronomical observations and cosmochemistry. The primary objective is to identify stellar scenarios that necessitate accurate nuclear reaction data, which significantly impact stellar evolution, and determine the most effective methods to obtain such data. The workshop will establish a collaborative framework and encourage joint activities among the participating scientists to facilitate the comparison of reaction studies using different and complementary techniques.

This workshop gathers specialists from theoretical and experimental condensed matter and atomic physics as well as nuclear and gravitational physics to discuss in an interdisciplinary way the concept of Bose-Einstein condensation and its realizations in different areas of the physical sciences. It is the 2024 edition (coinciding with the centenary of the pioneering first work by Satyendra Bose) of a series of key events that started in Levico (near Trento) back in 1993 and were instrumental to the impressive developments that research on BECs displayed in the last three decades. As compared to other events focussing on specific systems, the distinctive feature of our workshop will be its commitment to have a broad spectrum of participants and topics, with the goal of fostering and nurturing existing interdisciplinary connections and facilitating new, unexpected ones. In particular, themes will include condensation in gases of ultracold atoms, quasi-particles (magnons, excitons, polaritons) in solids, light; emergence of universality and criticality in the non-equilibrium statistical mechanics of condensates; condensates in gravitation and cosmology. The structure of the workshop will be designed with a specific attention to stimulate unexpected long-range connections between distinct fields.

Accelerator neutrino oscillation experiments have the potential to revolutionize our understanding of fundamental physics, including: characterizing charge-parity violation in the lepton sector; determining the neutrino mass ordering; and exploring physics beyond three-flavor neutrino mixing. However, the next generation of long baseline experiments (DUNE and Hyper-K) require precise control over the systematic uncertainties in their analyses. The most challenging uncertainties come from the modeling of neutrino-nucleus interactions and are related to subtle details of the pertinent nuclear physics, such as those of the target nucleus ground state, and the transport of hadrons through the nuclear medium. Confronting such uncertainties requires significantly improved theoretical models as well as targeted measurements with the current generation of experiments to inform model development. This workshop will bring together neutrino oscillation experimentalists, nuclear theorists and those measuring neutrino-nucleus interactions, and will provide a unique opportunity for cross-field discourse.

Kaonic, antiprotonic, muonic and pionic atoms, as well as the so-called “onia”, are exotic systems where one or more sub-atomic particles are replaced by a different particle of identical charge. In particular kaons, pions or antiprotons replacing one of the orbital electrons are used to form hadronic atoms, while a muon forms a leptonic exotic atom. Finally, in a “hydrogen-like” configuration, a bound pair of a particle and its antiparticle or of two leptons represents an exotic system called onium; some of these states, like muonium, positronium and pionium, have been already experimentally observed but others may exist; their observation could enable important tests for both QCD and QED. All these exotic atoms represent unique tools for testing the foundation of electromagnetic, strong and even gravitational interactions. It is thus the right time for discussing synergy and exchanging information between the physics communities involved in exotic atoms studies.
