Canonical c-field approach to interacting Bose gases: stochastic interference of matter waves
Holger Hauptmann, Walter T. Strunz
We present a stochastic matter field equation for an interacting many-body Bose system in equilibrium at ultracold finite temperature. Moreover, the proposed equation can be used f…

Bose-Einstein condensates in multiple well potentials from a variational path integral
Wattana Ratismith, Holger Hauptmann, Walter T. Strunz
We apply a path integral variational approach to obtain analytical expressions for condensate wave functions of an ultracold, interacting trapped Bose gases. As in many recent expe…
