Dynamics of Nonautonomous Matter Breather Wave in a Time-Dependent Harmonic Trap with Nonlinear Interaction Management
Abstract
In this paper, we study on breathers of Bose-Einstein condensate analytically in a time-dependent parabolic trap with a complex potential. It is found that the breather can be reflected by the parabolic potential or split into many humps and valleys with the time evolution. The nonlinear tunneling behavior of breather colliding on the parabolic potential is observed. The results provide many possibilities to manipulate breather experimentally in the condensate system.
