Time-dependent entropy of a cooling Bose gas
arXiv:2003.07795 · doi:10.1209/0295-5075/129/40006
Abstract
Exact analytic solutions of a nonlinear boson diffusion equation with suitable initial conditions that account for evaporative cooling of ultracold atoms, plus boundary conditions at the singularity are presented, and used to calculate the time-dependent entropy of a cold quantum gas.
