Dynamics of a driven optical lattice with distance-selective dissipation

We analyze the dynamics of Bose-Einstein condensates in a one-dimensional driven optical lattice in the presence of distance-selective dissipation. The interplay of on-site interactions, tunneling, external driving and dissipation dominates the feature of the dynamics. Relative atomic density on eac...

Description
Summary:We analyze the dynamics of Bose-Einstein condensates in a one-dimensional driven optical lattice in the presence of distance-selective dissipation. The interplay of on-site interactions, tunneling, external driving and dissipation dominates the feature of the dynamics. Relative atomic density on each site in the lattice and the standard deviation of the relative density are calculated. The effect of the distance-selective dissipation and an external driving on the diffusion of the atoms is analyzed. As a simple example, a BEC in a double-well potential, is analyzed in detail, and the steady state is analytically derived.
