RESOLUTION OF THE UNITY OF NORMALLY ORDERED GAUSSIAN OPERATOR FORM FOR CONSTRUCTING NEW QUANTUM MECHANICAL REPRESENTATIONS
Ma Shan-Jun
Abstract
A convenient approach for deriving new quantum mechanical representations is presented, that is, constructing the unity of normally ordered Gaussian operator forms and then decomposing it as projection operators. As examples, two two-mode complicated entangled state representations are derived by combining the coordinate eigenvector completeness and the coherent state.
