Phase Transition Dynamics

in Quantum Fluids

August 11-13, 2020, Sapporo, Japan


When an external parameter such as temperature, pressure, or some external field, is changed quickly, a physical system can become unstable and undergo a phase transition toward a different equilibrium state. The dynamics arising from this can involve various non-equilibrium processes, such as defect nucleation, phase separation or phase ordering. Collectively these various highly nonlinear and far-from-equilibrium processes are referred to as "phase transition dynamics". Phase transition dynamics is a central issue in many different fields of physics since it commonly occurs in nature at various scales. The aim of this conference is to discuss phase transition dynamics and related topics in all kinds of quantum fluids.

In the last few decades phase transition dynamics have become increasingly important in the field of quantum fluids. In particular, the dynamics of second-order phase transition or spontaneous symmetry breaking in superfluid helium and atomic Bose-Einstein condensates has attracted significant attention not only from low temperature physics, but also statistical physics, cosmology, and high energy physics. Hence, non-equilibrium dynamics of spontaneous symmetry breaking and related topics will be a central topics of the conference. The conference also intends to include works on the dynamics of first-order phase transitions, involving non-equilibrium processes of nucleation, growth dynamics of topological defects, solid-liquid transition, and other related phenomena.

This conference covers the following topics:

  • Phase ordering and domain coarsening dynamics (P)
  • Nucleation and growth of topological defects (N)
  • Statics and dynamics of topological defects (S)
  • Higgs/Amplitude and Nambu-Goldstone modes (H)
  • Other topics related to phase transition dynamics in quantum fluids (O)
  • Analogous systems in other condensed matter physics, cosmology and high energy physics (A)
