Abstract
Sympathetic cooling of an atomic Fermi gas by a Bose gas is studied by solu tion of the coupled quantum Boltzmann equations for the confined gas mixtur e. Results for equilibrium temperatures and relaxation dynamics are present ed, and some simple models are developed. Our study illustrates that a comb ination of sympathetic and forced evaporative cooling enables the Fermi gas to be cooled to the degenerate regime where quantum statistics and mean-he ld effects are important. The influence of mean-field effects on the equili brium spatial distributions is discussed qualitatively. [S1050-2947(99)0340 2-2].
