Crossover from 2D to 3D in a weakly interacting Fermi gas

Quantum Gases 2011-03-16 v2

Abstract

We have studied the transition from two to three dimensions in a low temperature weakly interacting 6^6Li Fermi gas. Below a critical atom number, N2DN_{2D}, only the lowest transverse vibrational state of a highly anisotropic oblate trapping potential is occupied and the gas is two-dimensional. Above N2DN_{2D} the Fermi gas enters the quasi-2D regime where shell structure associated with the filling of individual transverse oscillator states is apparent. This dimensional crossover is demonstrated through measurements of the cloud size and aspect ratio versus atom number.
