作为多体本征值问题的合作自发发射
Cooperative Spontaneous Emission as a Many Body Eigenvalue Problem
摘要：
本文研究了单光子从球对称的N个原子云（其中一个原子处于激发态，N-1个原子处于基态）中发射的问题，给出了这个多体问题的本征值和本征态的精确解析表达式。我们发现有些态的衰变速度比单原子的衰变速度快得多，而另一些态则被捕获并经历非常缓慢的衰变。当原子云的尺寸与辐射波长相比较小时，我们发现辐射频率发生了很大的偏移。
英文摘要：
We study emission of a single photon from a spherically symmetric cloud of N atoms (one atom is excited, N-1 are in ground state) and present an exact analytical expression for eigenvalues and eigenstates of this many body problem. We found that some states decay much faster then the single-atom decay rate, while other states are trapped and undergo very slow decay. When size of the atomic cloud is small compared with the radiation wave length we found that the radiation frequency undergoes a large shift.
