Abstract

The loading of a Bose-Einstein condensate into a deep 2D optical lattice provides a unique way to study 1D Bose gases: the strong radial confinement freezes any motion in two dimensions, and for deep enough lattices, the system can be seen as an array ofindependent 1D tubes. For our experimental parameters, the 1D gas is predicted to be in an intermediate regime between the Tonks-Girardeau and the Thomas-Fermi regime. We performed experiments showing that some long range phase coherence ispresent in this regime. We investigated correlation properties of these gases by studying their collective oscillations. In addition, we investigated the 1D Mott transition by adiabatically loading the 1D gases into a 1D optical lattice.
