无序的几何边界，如粗糙的表面诱导电磁量子真空的模式谱的重要修改。在类比安德森本地化的波诱导的随机势，在这里，我们表明，Casimir-Polder之间的相互作用的冷原子样品和粗糙表面也产生本地化现象。这些效应，代表了量子真空中无序的宏观表现，应该可以在粗糙表面附近的玻色-爱因斯坦凝聚体膨胀中观察到。
Disordered geometrical boundaries such as rough surfaces induce important modifications to the mode spectrum of the electromagnetic quantum vacuum. In analogy to Anderson localization of waves induced by a random potential, here we show that the Casimir-Polder interaction between a cold atomic sample and a rough surface also produces localization phenomena. These effects, that represent a macroscopic manifestation of disorder in quantum vacuum, should be observable with Bose-Einstein condensates expanding in proximity of rough surfaces.
