Production of a Fermi gas of atoms in an optical lattice

by G. Modugno, F. Ferlaino, R. Heidemann, G. Roati, M. Inguscio

Abstract:

We prepare a degenerate Fermi gas of potassium atoms by sympathetic cooling with rubidium atoms in a one-dimensional optical lattice. In a tight lattice, we observe a change of the density of states of the system, which is a signature of quasi two-dimensional confinement. We also find that the dipolar oscillations of the Fermi gas along the tight lattice are almost completely suppressed.
