摘 要: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.
关 键 词:two-mode squeezed even/odd coherent states quantum statistical properties
