摘　　要：In nanomechanical QED system,consisting of a charge qubit and a nanomechanical resonator with intrinsic nonlinearity,we study the temporal behavior of Rabi oscillation in the nonlinear Jaynes-Cummings model.Using microscopic master equation approach,we solve time evolution of the density operator describing this model.Also,the probability of excited state of charge qubit is calculated.These analytic calculations show how nonlinearity parameter and decay rates of two different excited states of the qubit-resonator system affect time-oscillating and decaying of Rabi oscillation.
