Dependent On The Time And Intensity Of Coupling The Jc Model In The Atomic Dynamical Behavior Of Quantum Properties

We have investigated the atomic dynamical behavior and atomic dipole squeezing phenomenon in the coupling of time-dependent and intensity-dependent Jaynes-Cummings model. The influence of the pulse length and cavity field intensity on the inversion of atomic population and atomic dipole squeezing are discussed when coupling of atomic and cavity field is time-dependent. The results show that this model's the time-evolution of the atomic population inversion and the atomic dipole squeezing is different from other intensity-dependent model, and that it can control effectively the atomic transition and quantum fluctuation by pulse width.
