DENSITY MATRIX AND PARTITION FUNCTION FOR A GENERALIZED NONDEGENERATE PARAMETRIC AMPLIFIER GAINED VIA A TYPE OF TWO-MODE SPECIAL SQUEEZED COHERENT STATE REPRESENTATION

Hong-Yi Fan, Yue Fan, Mingzhai Sun

By introducing a type of two-mode special squeezed coherent state, we directly derive the density matrix and partition function for a generalized nondegenerate parametric amplifier. The derivation is neat because the states make up a new, complete representation.

Unequal-power amplitude squeezing of a special type of multimode functional superposition state light field

Liu Bao-ying

A special type of multimode functional superposition state light field is structured which is composed of multimode functional coherent state, multimode complex conjugation functional coherent state and their contrary states by equal intensity. The properties of unequal-power amplitude squeezing of the state ｜ψ~((4))_(f_j)〉_q is studied, and it is found that the squeezing degree and depth of each mode of the state are decided by the spatial distribution function of classical intensity of each mode of the state ｜ψ~((4))_(f_j)〉_q. Especially, the unequal-power amplitude squeezing properties are asymmetrical, nonlinear and anisotropic with the change of the spatial distribution function of classical initial phase and classical intensity of each mode of the state (｜ψ~((4))_(f_j)〉_q).
