散斑势中物质波的热化
Thermalization of matter waves in speckle potentials
摘要：
我们表明，突然释放的非线性物质波的动量分布与有限的速度在散斑电位收敛，经过一个平衡的演变，一个普遍的瑞利-金斯热分布。通过探索平衡波的完整相图，我们发现，对于低但非零值的无序强度，一个大尺度结构-凝聚-出现在平衡分布。
英文摘要：
We show that the momentum distribution of a nonlinear matter wave suddenly released with a finite velocity in a speckle potential converges, after an out-of-equilibrium evolution, to a universal Rayleigh-Jeans thermal distribution. By exploring the complete phase diagram of the equilibrated wave, we discover that for low but nonzero values of the disorder strength, a large-scale structure -a condensate- appears in the equilibrium distribution.
