New approach for solving master equations of density operator for the Jaynes Cummings Model with Cavity Damping

摘要

By introducing thermal entangled state representation which can map masterequations of density operator in quantum statistics as state vector evolutionequations and using dissipative interaction picture we solve the masterequation of J-C model with cavity damping. In addition we derive the Wignerfunction for density operator when the atom is initially in the up state andthe cavity mode is in coherent state.
