The resulting potential consists of a lattice of tightly confining tubes; each filled with a 1D quantum gas. Tunnel coupling between neighboring tubes is controlled by the intensity of the laser fields.

The lifetime of the condensate in the lattice and the dependence of the interference pattern on the lattice configuration are investigated.
