Operators'' s-parameterized ordering and its classical correspondence in quantum optics theory

In reference to the Weyl ordering , where X and P are coordinate and momentum operator, respectively, this paper examines operators' s-parameterized ordering and its classical correspondence, finds the fundamental function-operator correspondence and its complementary relation , where Hm,n is the two-variable Hermite polynomial, are bosonic annihilation and creation operators respectively, s is a complex parameter. The s'-ordered operator power-series expansion of s-ordered operator in terms of the two-variable Hermite polynomial is also derived. Application of operators' s-ordering formula in studying displaced-squeezed chaotic field is discussed.
