Abstract

We introduce a new (to our best knowledge) type of squeezing-enhanced thermal states (SETS) that is generated by operating a new two-parameter generalized squeezing operator on a thermal (chaotic) field. By using the operator’s Weyl-ordering invariance under the similarity transformation and the Weyl correspondence scheme, we derive the normally ordered form of the density operator of SETS. Based on it, we study the resulting squeezing effects of the SETS and investigate its statistical properties by the second-order correlation function, photon-number distribution, and the Wigner function. Compared with the usual squeezed thermal state, SETS exhibits stronger squeezing and some new statistical properties. We find that the effect of the new type of squeezing operator is rotated squeezing.
