New approach to solving master equations of density operator for the Jaynes Cummings model with cavity damping

doi:10.1088/1674-1056/23/9/090303

Abstract By introducing thermo-entangled state representation |η>, which can map master equations of density operator in quantum statistics as state-vector evolution equations, and using “dissipative interaction picture” we solve the master equation of Jaynes-Cummings model with cavity damping. In addition we derive the Wigner function for density operator when the atom is initially in the up state |↑> and the cavity mode is in coherent state.

Keywords: Jaynes-Cummings model entangled state representation master equations
