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.
我们利用一个可精确求解的模型表明，通过与热库的碰撞，双势阱玻色-爱因斯坦凝聚（BEC）中会产生非线性动力学。这种动力学可以促进相位或数压缩的产生，并且在更长的时间内，可以产生宏观的非经典叠加态。通过将储库原子加载到光学晶格中，可以增强这些效应。
