Boltzmann equation simulation for a trapped Fermi gas of atoms    [PDF]

Olga Goulko, Frédéric Chevy, Carlos Lobo
The dynamics of an interacting Fermi gas of atoms at sufficiently high
temperatures can be efficiently studied via a numerical simulation of the
Boltzmann equation. In this work we describe in detail the setup we used
recently to study the oscillations of two spin-polarised fermionic clouds in a
trap. We focus here on the evaluation of interparticle interactions. We compare
different ways of choosing the phase space coordinates of a pair of atoms after
a successful collision and demonstrate that the exact microscopic setup has no
influence on the macroscopic outcome.
