Spontaneous Emission in Chaotic Cavities
Abstract
The spontaneous emission rate of a two-level atom inside a chaotic cavity fluctuates strongly from one point to another because of fluctuations in the local density of modes. For a cavity with perfectly conducting walls and an opening containing N wavechannels, the distribution of is given by P() N/2-1(+0)-N-1, where 0 is the free-space rate. For small N the most probable value of is much smaller than the mean value 0.
