Query: Evaporative cooling and self-thermalization in an open system of
  interacting fermions   We study depletion dynamics of an open system of weakly interacting fermions
with two-body random interactions. In this model fermions are escaping from the
high-energy one-particle orbitals, that mimics the evaporation process used in
laboratory experiments with neutral atoms to cool them to ultra-low
temperatures. It is shown that due to dynamical thermalization the system
instantaneously adjusts to the new chemical potential and temperature, so that
occupation numbers of the one-particle orbitals always obey the Fermi-Dirac
distribution. In this way we are able to describe the evaporation process which
leads to a significant cooling of particles remaining inside the system. We
also briefly discuss the evaporation process in the SYK black hole model that
corresponds to strongly interacting fermions.
