Аннотация: Finite topological quantum systems can undergo continuous metastable quantum phase transitions to change their topological nature. Here we show how to nucleate the transition between ring currents and dark soliton states in a toroidally trapped Bose-Einstein condensate. An adiabatic passage to wind and unwind its phase is achieved Показать полностьюby explicit global breaking of the rotational symmetry. This could be realized with current experimental technology.
