Understanding the non-equilibrium evolution of core-collapse supernovae and the early Universe is a long-standing problem. In these systems, high-energy elementary particles, such as chiral/Dirac fermions, play essential roles: neutrinos in supernovae, quarks in quark-gluon plasmas, and potentially additional BSM particles in the early Universe. The chiral/Dirac fermions also appear emergently in condensed matter systems known as Weyl/Dirac semimetals. These systems share that hydrodynamics and kinetic theory, as a universal theoretical framework, are applied to describe time evolution.

This 3-day workshop brings together researchers working in particle physics, nuclear physics, astrophysics, cosmology, and condensed matter physics with interest in the early Universe, supernovae, and neutron stars. The workshop aims to overview the current status and problems in each field and discuss potential interdisciplinary future directions in a stimulating and collaborative environment.
