Sodium Bose-Einstein Condensates in an Optical Lattice

Abstract

The phase transition from a superfluid to a Mott insulator has been observed in a 23^{23}Na Bose-Einstein condensate. A dye laser detuned 5\approx 5nm red of the Na 323^2S32 \to 3^2P1/2_{1/2} transition was used to form the three dimensional optical lattice. The heating effects of the small detuning as well as the three-body decay processes constrained the timescale of the experiment. Certain lattice detunings were found to induce a large loss of atoms. These loss features were shown to be due to photoassociation of atoms to vibrational levels in the Na2_2 (1)3Σg+(1) ^3\Sigma_g^+ state.
