界面附近自发发射的玻色子增强
Bosonic enhancement of spontaneous emission near an interface
摘要：
我们展示了如何激发的二能级原子的自发发射率放置在一个被困的玻色-爱因斯坦凝聚体的基态原子的玻色刺激增强。这种激励依赖于激发的物质波包与宏观占据的凝聚波函数的重叠，并提供了玻色气体的空间相干性的探测。这种效应可以用来放大界面附近受激原子的距离依赖性衰变率。
英文摘要：
We show how the spontaneous emission rate of an excited two-level atom placed in a trapped Bose-Einstein condensate of ground-state atoms is enhanced by bosonic stimulation. This stimulation depends on the overlap of the excited matter-wave packet with the macroscopically occupied condensate wave function, and provides a probe of the spatial coherence of the Bose gas. The effect can be used to amplify the distance-dependent decay rate of an excited atom near an interface.
