Creating nonclassical states of Bose-Einstein condensates by dephasing collisions.

%A Nir Bar-Gill %A Rao, D %A Gershon Kurizki %X We show, using an exactly solvable model, that nonlinear dynamics is induced in a double-well {Bose-Einstein} condensate {(BEC)} by collisions with a thermal reservoir. This dynamics can facilitate the creation of phase or number squeezing and, at longer times, the creation of macroscopic nonclassical superposition states. Enhancement of these effects is possible by loading the reservoir atoms into an optical lattice. %B Physical review letters %V 107 %G eng
