摘要

本文从理论上讨论了运用动态的腔环境实现对处于激发态的两能级原子自发辐射过程的调控.研究发现,周期性地改变与原子相互作用的腔环境导致电磁模式之间相互作用,产生电磁模式密度重新分配,并使得原子与腔环境之间的能量交换的频率以及能量耗散的速度发生改变;当腔环境的变化频率和原子、环境之间交换能量的过程保持相对一致时可以实现稳定的相干性演化,衰减效应受到显著的抑制,进而可以通过环境变化操纵相干态的演化.

In the paper, we theoretically discuss the use of dynamic cavity environment to realize controlling of the evolution of spontaneous emission from an excited two-level atom. It is found that cyclical changes in cavity environment leads to the interaction betwcen the electromagnetic modes, resulting in the redistribution of the electromagnetic modes density; both the frequency of energy exchange and the energy dissipation rate between atom and environment are affected. When the frequency of environment change is relatively accordant with the process of energy exchange between the atom and environment, the decay rate is obviously inhibited and a stable coherence evolution can be obtained. Thus the evolution of coherent states can be modulated by using dynamic environment changes.
