摘要
The relative phase of two initially independent Bose-Einstein condensates can be laser cooled to unite the two condensates by putting them into a ring cavity and coupling them with an internal Josephson junction. First, we show that this phase cooling process already appears within a semiclassical model. We calculate the stationary states, find regions of bistable behavior and suggest a Ramsey-type experiment to measure the build up of phase coherence between the condensates. We also study quantum effects and imperfections of the system.
