THE SQUEEZING PROPERTIES IN THE JAYNES-CUMMINGS MODEL WITH ARBITRARY INTENSITY-DEPENDENT COUPLING

We have studied the squeezing properties of the atom and the radiation field in arbitrary intensity-dependent-coupling Jaynes-Cummings model when it is restricted to the following initial condition: the atom in its coherent state and the field in the vacuum state. The influence o f virtual-photon processes on the atomic squeezing predicted by the Ja ynes-Cummings model (JCM) has been examined. The relationship between the field and atomic squeezing in the resonant multi-photon JCM has be en discussed. The symmetry between the field and atomic squeezing (SFA S) has been exposed in the resonant vacuum one-photon JCM, and the inf luence of non-resonant interaction and virtual-photon processes on the SFAS has also been discussed.
