Abstract

The evaporative cooling, very successful in the bosonic case, is not efficient for fermions because in this case the 5-wave scattering cross section vanishes in the limit of low temperatures. However, the recent progress in sympathetic cooling [1] opens a possibility to trap and cool to ultra-low temperatures the atomic Fermi gas as well. As the trapped Fermi gas is not homogeneous because of the presence of the external potential its properties are essentially modified as compared to the translationally invariant electron gas in solids.
