中文摘要：

We investigate the nonlinear dissipative coherence bifurcation and population dynamics of a two-component atomic Bose–Einstein condensate coupling with a continuum.The coupling between the two-component condensates and the continuum brings effective dissipations to the two-component condensates.The steady states and the coherence bifurcation depend on both dissipation and the nonlinear interaction between condensed atoms.The coherence among condensed atoms may be even enhanced by the effective dissipations.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.

We investigate the nonlinear dissipative coherence bifurcation and population dynamics of a two-component atomic Bose-Einstein condensate coupling with a continuum. The coupling between the two-component condensates and the continuum brings effective dissipations to the two-component condensates. The steady states and the coherence bifurcation depend on both dissipation and the nonlinear interaction between condensed atoms. The coherence among condensed atoms may be even enhanced by the effective dissipations. 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.
