Interference patterns of Bose-condensed gases in a two-dimensional optical lattice
Interference patterns of Bose-condensed gases in a two-dimensional optical lattice
For the Bose-condensed gas confined in a magnetic trap and in a two-dimensional optical lattice, the non-uniform distribution of atoms in different lattice sites is considered based on Gross-Pitaevskii equation. A propagator method is used to investigate the time evolution of 2D interference patterns after (i)only the optical lattice is …
