Limits to Sympathetic Evaporative Cooling of a Two-Component Fermi Gas
arXiv:cond-mat/9909014 · doi:10.1103/PhysRevA.61.053602
Abstract
We find a limit cycle in a quasi-equilibrium model of evaporative cooling of a two-component fermion gas. The existence of such a limit cycle represents an obstruction to reaching the quantum ground state evaporatively. We show that evaporatively the βμ~ 1. We speculate that one may be able to cool an atomic fermi gas further by photoassociating dimers near the bottom of the fermi sea.
