Hermitian Operators Conjugate to Two-Mode Number-Difference Operator Studied in Entangled State Representation
Xuefen Xu
Abstract
In similar to the derivation of phase angle operator conjugate to the number operator by Arroyo Carrasco–Moya Cessay we deduce the Hermitian phase operators that are conjugate to the two-mode number-difference operator and the three-mode number combination operator. It is shown that these operators are on the same footing in the entangled state representation as the one of Turski in the coherent state representation.
