We study correlations of atomic density in a weakly interacting Bose-Einstein condensate, expanding diffusively in a random potential. We show that these correlations are long range and that they are strongly enhanced at long times. The density at distant points exhibits negative correlations.
我们研究了在随机势中扩散膨胀的弱相互作用玻色 - 爱因斯坦凝聚体中原子密度的相关性。我们表明这些相关性是长程的，并且在长时间时会强烈增强。远处点的密度呈现负相关。
