Phys. Rev. A 63, 033603 (2001) [5 pages]Adiabatic compression of a trapped Fermi gasReceived 27 September 2000; published 5 February 2001 We propose a method to reach conditions of high degeneracy in a trapped Fermi gas, based on the adiabatic transfer of a small fraction of atoms from a magnetic to a tighter optical trap. The transformation yields a large increase of the Fermi energy, without a significant change of the temperature. The large enhancement of the central density emphasizes the role of the interactions and makes the system much closer to the BCS transition. We show that, despite Pauli blocking, the thermalization processes ensuring equilibrium in the optical trap are not suppressed at low temperature. © 2001 The American Physical Society URL:
