Non-equilibrium BEC in an optical lattice: interplay of disorder and interactions
Stationary and dynamical properties within the decoupling approximation and the one-level band scheme.
The interplay of interactions and dynamical structural disorder in a BEC confined in an optical lattice is studied. The atoms can move in an array of optical Josephson junctions that can be varied in time in the form of Landau-Zener sweeps. In addition, the particles are subject to an inhomogeneous harmonic field.
We study stationary and dynamical properties within the decoupling approximation and the one-level band scheme. A dynamical phase diagram summarizes the final situation across ground state and inverse sweeps is given in terms of the effect of disorder, interaction, and the speed of the sweeps.
