Dynamics of Hysteresis for a Bose–Einstein Condensate Soliton in a Dynamic Trap

Аннотация

The dynamics of the fundamental soliton of Bose–Einstein atomic condensate is analytically and numerically examined and compared in two schemes: (i) a magnetic or an optical trap with oscillating walls and (ii) a single oscillating atomic mirror in a homogeneous gravitational field. It is demonstrated that the dependence of the degree of excitation of the soliton motion on the rate of scanning of the instantaneous oscillation frequency has a band structure.
