Evaporative depolarization and spin transport in a unitary trapped Fermi gas
Evaporative depolarization and spin transport in a unitary trapped Fermi gas
We consider a partially spin-polarized atomic Fermi gas in a high-aspect-ratio trap, with a flux of predominantly spin-up atoms exiting the center of the trap. We argue that such a scenario can be produced by evaporative cooling, and we find that it can result in a substantially nonequilibrium polarization pattern …
