Phase Separation in two-Species Atomic Bose-Einstein Condensate with Interspecies Feshbach Resonance

Lu Zhou, Jing Qian, Han Pu +2

We consider a mixture of two-species atomic Bose-Einstein codensates coupled to a bound molecular state at zero temperature via interspecies Feshbach resonance. The interspecies Fe…
