Observation of Reduced Three-Body Recombination in a Fermionized 1D Bose Gas |

| Abstract: |
We investigate correlation properties of a one-dimensional interacting Bose gas by loading a mangnetically trapped 87Rb Bose-Einstein condensate into a deep two-dimensional optical lattice. We measure the three-body recombination rate for both the BEC in the magnetic trap and the BEC loaded into the optical lattice. The recombination rate coeffient is a factor of seven smaller in the lattice, which we interpret as a reduction in the local three-body correlation function in the 1D case. This is a signature of correlation intermediate between that of the uncorrelated phase coherent 1D mean-field regine and the strongly correlated Tonks-Girardeau regime. |
