Crossover from 2D to 3D in a Weakly Interacting Fermi Gas
Crossover from 2D to 3D in a Weakly Interacting Fermi Gas
We have studied the transition from two to three dimensions in a low temperature weakly interacting $^6$Li Fermi gas. Below a critical atom number, $N_{2D}$, only the lowest transverse vibrational state of a highly anisotropic oblate trapping potential is occupied and the gas is two-dimensional. Above $N_{2D}$ the Fermi gas …
