Dynamics of spinor Bose-Einstein condensate subject to dissipation

We investigate the internal dynamics of the spinor Bose-Einstein condensates subject to dissipation by solving the Lindblad master equation. It is shown that for the condensates without dissipation its dynamics always evolve along a specific orbital in the phase space of （no, O） and display three ki...

Summary:We investigate the internal dynamics of the spinor Bose-Einstein condensates subject to dissipation by solving the Lindblad master equation. It is shown that for the condensates without dissipation its dynamics always evolve along a specific orbital in the phase space of （no, O） and display three kinds of dynamical properties including Josephson-like oscil- lation, self-trapping-like oscillation, and ＇running phase＇. In contrast, the condensates subject to dissipation will not evolve along the specific dynamical orbital. If component-1 and component-（-1） dissipate at different rates, the magnetization m will not conserve and the system transits between different dynamical regions. The dynamical properties can be exhibited in the ohase soace of （nn, θ, m）.
