Multistability and critical fluctuation in a split Bose-Einstein condensate
发表期刊COMMUNICATIONS IN THEORETICAL PHYSICS
关键词Phase Diffusion
摘要By using a two-mode description, we show that there exist the multistability, phase transition and associated critical fluctuations in the macroscopic tunnelling process between the halves of a double-well trap containing a Bose-Einstein condensate the phase transition that two of the triple stable states and an unstable state merge into one stable state or a reverse process takes place whenever the ratio of the mean field energy per particle to the tunnelling energy goes across a critical value of order one. The critical fluctuation phenomenon corresponds to squeezed states for the phase difference between the two wells accompanying with large fluctuations of atom numbers.
