Abstract

By virtue of the entangled state representation and the technique of integration within an ordered product (IWOP) of operators we derive some new two-variable Hermite-polynomial-operator identities, their application for calculating moment and cumulant for two-mode quadratures in quantum field theory are presented. The new operator identities make all calculations neat and concise.
