This program brought together experts from three key areas: nuclear physics (NP), atomic, molecular, and optical physics (AMO), and quantum information science (QIS). The aim was to foster interdisciplinary research and advance discovery into the physics of quantum few- and many-body systems. Participants also explored both the challenges and opportunities presented by emerging quantum technologies, particularly in the simulation of low-dimensional and few-body systems.
The program spanned five weeks and included an embedded workshop during the third week. Activities were designed to promote collaboration and enhance community engagement among the three subfields. Emphasis was placed on shared methodologies, the emergence of universal behaviors across different systems and energy scales, and the connections between few-body physics and QIS.
Among the highlights of the program: 1) We had several talks reporting latest advances in the understanding of universality in three- and four-body systems and how these results relate to Efimov physics; 2) We heard about calculations of resonances, scattering and reactions in hadronic and nuclear systems and discussed common challenges at different energy scales and how to move forward in bridging few- and many-body methods; 3) There were presentations on few- and manybody calculations clustered and exotic nuclei, including neutron-reach helium and boron isotopes; 4) We heard about and discussed recent developments utilizing concepts of machine learning/artificial intelligence (AI/ML) and QIS to formulate new methods for describing of ultracold Fermi gases and nuclear systems, as well as the latest advances in the quantum simulation of cold atoms and nuclear dynamics.
