Phase Separation and Pattern Formation in a Binary Bose-Einstein Condensate

Phase Separation and Pattern Formation in a Binary Bose-Einstein Condensate

The miscibility-immiscibility phase transition in binary Bose-Einstein condensates (BECs) can be controlled by a coupling between the two components. Here we propose a new scheme that uses coupling-induced pattern formation to test the Kibble-Zurek mechanism (KZM) of topological-defect formation in a quantum phase transition. For a binary BEC in a …
