Abstract: | Two new types of quantum states are constructed by applying the
operator s(ξ)=exp(ξ*ab-ξa?b?) on the two-mode even and odd coherent states. The mathematical and quantum statistical
properties of such states are investigated. Various nonclassical
features of these states, such as squeezing properties, the
inter-mode photon bunching, and the violation of Cauchy-Schwarz
inequality, are discussed. The Wigner function in these states are
studied in detail. |
