Amplitude-squared squeezing in the multiphoton Jaynes-Cummings model

M. H. Mahran, A.‐S. F. Obada

Amplitude-squared squeezing has been investigated for the generalized multiphoton Jaynes-Cummings model. Different values for the initial photon numbers as well as different photon multiplicities have been used. The atom is taken to be in either the ground or the excited state. The relation between both amplitude-squared and normal squeezing and the phenomenon of collapse and revival has been discussed.

Amplitude-squared squeezing in the multiphoton Jaynes-Cummings model: Effects of the atomic coherent states and detuning

Mubeen A. Mir

An analysis of the effects of detuning and the superposition angle on amplitude-squared (AS) squeezing is presented for the one- and two-photon 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 input in a small range of values of the detuning. The superposition angle affects the degree of AS squeezing more significantly for a detuned field than for a tuned one. The behavior of AS squeezing becomes independent of the value of the superposition angle in both the models for large initial average photon number, n\ifmmode\bar\else\textasciimacron\fi{}, with any value of detuning and for large detuning with any value of n\ifmmode\bar\else\textasciimacron\fi{}.
