Abstract

The correlation properties of a one-dimensional interacting Bose gas by loading a magnetically trapped ⁸⁷Rb Bose-Einstien condensate (BEC) into a deep two-dimensional optical lattice were investigated. The three-body recombination rate was measured for both the BEC in the magnetic trap and the BEC loaded into the optical lattice. It was found that the recombination rate coefficient was a factor of 7 smaller in the lattice, which was interpret as a reduction in the local three-body correlation function in the 1D case. The results show a signature of correlation intermediate between that of the uncorrelated, phase coherent, 1D, mean-field regime and the strongly correlated Tonks-Girardeau regime.
