Spontaneous emission from an atom in a nonideal cavity: Application of a generalized master equation
R.W.F. van der Plank, L.G. Suttorp · Physical Review A · 1996
The decay of an excited two-level atom in a cavity with mirrors of finite transmittivity is studied with the help of a generalized multimode master equation that has been established recently. The time evolution of the decaying atom is obtained by accounting for the interaction with infinitely many quasimodes. The analytical and numerical results are compared with those of the standard multimode master equation and of a universe-mode approach. \textcopyright{} 1996 The American Physical Society.
