Past Workshops

The renormalization group plays a fundamental role in many areas of physics. Various aspects of perturbative and non-perturbative renormalization have been extensively investigated for decades in different physics contexts. Yet, knowledge gained in one area is often not completely appreciated by experts working on other topics.

The topic of this workshop is the “X17” particle, whose existence has been claimed in a series of recent experiments. In the workshop, the current status of the new experimental research and the new advances of the theoretical studies about this hypothetical particle will be presented and discussed.

The Electron-Ion Collider (EIC) will open a new frontier in exploring the internal dynamics of hadrons and nuclei, offering precision access to the three-dimensional structure of matter. Transverse Momentum Dependent (TMD) distributions are essential tools for interpreting EIC observables, but the theoretical landscape behind them remains fragmented.

The study of charmonium, a system containing a charm quark-anti-quark pair underwent a revolution after a number of entirely unexpected narrow resonances called the Xs, Ys and Zs were discovered by experiments at the start of the new millennium. The nature of these resonances is still unclear. Similarly, interest in glueballs, hadrons made predominantly of confined gluons, has recently been rekindled.

The search of neutrinoless double-β decay involves substantial effort from both experimental and theoretical researchers. This yet-unobserved process requires highly sensitive detectors on the experimental side, and computationally intensive, high-precision calculations of the nuclear matrix element on the theoretical side.

Methods to simulate physics systems simultaneously across a range of temperatures provide a natural way to study thermodynamic phases, phase transitions, and criticality in many systems. These multi-canonical methods already represent a very promising approach for upcoming lattice field theory (LFT) calculations, and ongoing research is working towards achieving state-of-the-art applications. Recently, additional momentum has been generated by new connections to machine learning (ML) methods. This workshop aims to bring together the community of researchers working on developments in multi-canonical methods, both within LFT and in other domains, with the objective of cross-pollinating ideas and identifying future directions for this field. Key topics to be discussed include density-of-states methods, nested sampling, parallel tempering, out-of-equilibrium simulation, and connections to flow and diffusion ML models.

This workshop will gather leading international researchers in nuclear physics, statistics, and applied mathematics to explore and discuss how new and existing statistical methods can enable progress on the frontiers of nuclear physics, spawn new directions for the field, and catalyze techniques that ensure maximum & reliable use of data taken in nuclear-physics experiments.

Neutron capture reactions play a dominant role in several astrophysical processes, in particular for the synthesis of heavy elements. The traditional slow (s) and rapid (r) neutron-capture processes include neutron capture reactions along the valley of stability and all the way out to the extremes of the nuclear chart. Additional processes have been proposed recently to account for astronomical and stardust observations, namely the intermediate (i) process and the n process. Disentangling the contributions from the various processes requires a good handle of the nuclear data input. Neutron-capture reactions are one of the most uncertain properties since the relevant reactions cannot be measured directly on short-lived nuclei. The workshop will bring together astrophysics modelers who identify the important neutron-capture reactions, nuclear theorists who predict their cross sections and experimentalist focusing both on direct and indirect measurements.

The study of short-lived states, whether at the edge of nuclear stability or just above a reaction threshold, represents a complex and multifaceted domain where few-body physics emerges from the interactions of many nucleons. Recent years have seen a surge in experimental observations that continue to challenge our current models of the nucleus. As instrumentation advances rapidly, a widening gap has emerged between nuclear modeling capabilities and the data being collected.

Superconducting devices have gained increasing attention over the past decade as powerful platforms for quantum optics as well as quantum information processing. In particular, superconducting circuits based on non-linear elements, such as Josephson junctions and high kinetic inductance materials, are opening up a new regime for quantum optics experiments at microwave frequencies and quantum analog simulators. The workshop "Superconducting Quantum Devices for Quantum Optics and Quantum Simulations" will address: (i) microwave quantum optics for circuit-QED experiments, (ii) quantum simulation based on superconducting circuits for nuclear physics applications; and (iii) novel detector concepts for astrophysics and particle physics. The workshop aims at bringing together young and senior researchers in the field, as well as international theoreticians and experimentalists to foster exchange and spark ideas for new projects and collaborations, advancing the field of superconducting quantum devices.
