Huai-Xin Lu, Zeng‐Bing Chen, YONG-DE ZHANG · Modern Physics Letters B · 2002
Using the decomposition theorm of superoperators, an explicit solution of the master equation for an attenuated or amplified nonlinear oscillator is presented. It is found that the time evolution of the density operator can be easily obtained from an arbitary initial state using this method.
