Beyond mean-field dynamics in open Bose-Hubbard chains
D. Witthaut, F. Trimborn, H. Hennig +3
We investigate the effects of phase noise and particle loss on the dynamics of a Bose-Einstein condensate in an optical lattice. Starting from the many-body master equation, we dis…

On the effective Dirac dynamics of ultracold atoms in bichromatic optical lattices
D. Witthaut, T. Salger, S. Kling +2
We study the dynamics of ultracold atoms in tailored bichromatic optical lattices. By tuning the lattice parameters, one can readily engineer the band structure and realize a Dirac…

Mean-field dynamics of a two-mode Bose-Einstein condensate subject to noise and dissipation
F. Trimborn, D. Witthaut, S. Wimberger
We discuss the dynamics of an open two-mode Bose-Hubbard system subject to phase noise and particle dissipation. Starting from the full many-body dynamics described by a master equ…
