Coherence and dynamics of a two-component condensate coupling with a continuum
Year: 2012
Type: preprint
Abstract: We investigate the many-body coherence and population dynamics of a two-component atomic Bose-Einstein condensate coupled with a continuum. We reveal that the combination of dissipation and nonlinearity may induce different steady states and modify the bifurcation of coherence. The steady states depend on the relative dissipation strengths. The coherence may be even enhanced by the dissipation effects. The combination of dissipation and nonlinearity allows one to control the switching between different self-trapped states or the switching between a self-trapped state and a non-self-trapped state. This opens an alternative route for manipulating coherence and population transition in an open many-body system via dissipation and nonlinearity.
