    "abstract": "By using a two-mode description, we show that there exist the multistability,\nphase transition and associated critical fluctuations in the macroscopic\ntunneling process between the halves of a double-well trap containing a\nBose-Einstein condenstate. The phase transition that two of the triple stable\nstates and a unstable state merge into one stable state or a reverse process\ntakes place whenever the ratio of the mean field energy per particle to the\ntunneling energy goes across a critical value of order one. The critical\nfluctuation phenomenon corresponds to squeezed states for the phase difference\nbetween the two wells accompanying with large fluctuations of atom numbers.",
