Non-Markovian dynamics in atom-laser outcoupling from a double-well Bose–Einstein condensate

Abstract

We investigate the dynamics of a continuous atom laser based on the merging of independently formed atomic condensates. In a first attempt to understand the dynamics of the system, we consider two independent elongated Bose–Einstein condensates which approach each other and focus on intermediate inter-trap distances so that a two-mode model is well justified. In the framework of a mean-field theory, we discuss the quasi-steady-state population of the traps as well as the energy distribution of the outcoupled atoms.
