Abstract
We discuss the controlled generation of topological flows for an ultracold atomic Bose gas in a toroidal trap configuration using the method of phase imprinting. Starting from a stationary kink state, we show theoretically and numerically that angular momentum can be added to the gas in a spatio-temporally controlled way in order to excite transitions between kink states with different average angular momenta.
