| Abstract: | In similar to the derivation of phase angle operator conjugate to the numberoperator by Arroyo Carrasco-Moya Cessay we deduce the Hermitian phaseoperators that are conjugate to the two-mode number-difference operator andthe three-mode number combination operator. It is shown that these operatorsare on the same footing in the entangled state representation as the one ofTurski in the coherent state representation. |
