Entropic uncertainty in two two-level atoms interacting with a cavity field in presence of degenerate parametric amplifier
Original language description
The analytical solution of the problem of two two-level atoms with degenerate two-photon transitions interacting with a single-mode radiation field in the presence of a parametric amplifier term is presented. The purity of the atomic state has been usedto measure the degree of entanglement between the atom and the field. The temporal evolution of variance and entropy squeezing as well as atomic inversion for the single-atom case are studied. It has been shown that maximum squeezing for the variance andentropy squeezing occurs when the ratio between the amplifier coupling lambda(3) and the field frequency omega equals 0.26. Increasing the value of the ratio lambda(3)/omega further leads to the vanishing of squeezing from the system. It is also noted that the existence of the coupling parameter results in the system never reaching the pure state except at the points of revival times.
