AMPLITUDE-SQUARED SQUEEZING IN THE MULTIPHOTON JAYNES-CUMMINGS MODEL - EFFECTS OF THE ATOMIC COHERENT STATES AND DETUNING

An analysis of the effects of detuning and the superposition angle on amplitude-squared (AS) squeezing is presented for the one- and two-pho ton Jaynes-Cummings model (JCM) using coherent and squeeze inputs. In the one-photon JCM for squeezed inputs, it is shown that the degree of AS squeezing increases as the detuning increases. The two-photon JCM, on the other hand, displays this characteristic only for coherent inp ut in a small range of values of the detuning. The superposition angle affects the degree of AS squeezing more significantly for a detuned f ield than for a tuned one. The behavior of AS squeezing becomes indepe ndent of the value of the superposition angle in both the models for l arge initial average photon number, nBAR, with any value of detuning a nd for large detuning with any value of nBAR.
