Quench Dynamics of Bose-Einstein Condensates in Boxlike Traps
文献摘要：
By quenching the interatomic interactions,we investigate the nonequilibrium dynamics of two-dimensional Bose-Einstein condensates in boxlike traps with power-law potential boundaries.We show that ring dark solitons can be excited during the quench dynamics for both concave and convex potentials.The quench's modulation strength and the steepness of the boundary are two major factors influencing the system's evolution.In terms of the number of ring dark solitons excited in the condensate,five dynamic regimes have been identified.The condensate undergoes damped radius oscillation in the absence of ring dark soliton excitations.When it comes to the appearance of ring dark solitons,their decay produces interesting structures.The excitation patterns for the concave potential show a nested structure of vortex-antivortex pairs.The dynamic excitation patterns for the convex potential,on the other hand,show richer structures with multiple transport behaviors.
