Abstract:
We consider BECs on 1D rings at zero temperature stirred by a link. Their spectrum is theoretically analyzed, consisting in dark and gray solitonic trains, and vortex states comoving with the link. We show how to produce these states by adiabatically stirring the condensate from its ground sate: through specific cycles where the velocity and the strength of the link are gradually tuned. The general properties of the spectrum and cycles are studied through the Gross-Pitaevskii equation with a delta-type link and in the comoving frame. A set of specific cycles to excite the BEC are reproduced by simulations of the time-dependent Gross-Pitaevskii with a rotating Gaussian link. More on arXiv:1907.04574.
