Simple method for excitation of a Bose-Einstein condensate
arXiv:quant-ph/0107020 · doi:10.1103/PhysRevA.65.013604
Abstract
An appropriate, time-dependent modification of the trapping potential may be sufficient to create effectively collective excitations in a cold atom Bose-Einstein condensate. The proposed method is complementary to earlier suggestions and should allow the creation of both dark solitons and vortices.
