摘要：

Normal squeezing, variance and entropy squeezing factors based on the Heisenberg uncertainty principle and Shannon information entropy theory, respectively, derived from the entangled states of two-mode coherent states in two-photon processes are numerically investigated through a previously developed generalized nonlinear Jaynes-Cummings two-level spin model. Numerical simulations are performed and discussed for two-two-photon model Hamiltonians in both resonant and off-resonant states of the spin system with the bimodal cavity field.
