Perturbative corrections to the Gutzwiller mean-field solution of the Mott-Hubbard model
C. Schroll, Florian Marquardt, C. Bruder
We study the Mott-insulator transition of bosonic atoms in optical lattices. Using perturbation theory, we analyze the deviations from the mean-field Gutzwiller ansatz, which becom…

Decoherence of cold atomic gases in magnetic micro-traps
C. Schroll, W. Belzig, C. Bruder
We derive a model to describe decoherence of atomic clouds in atom-chip traps taking the excited states of the trapping potential into account. We use this model to investigate dec…
