| Abstract: | Hermitian phose operators in a finit-dimensional space are further investigated in tems of the Pegg and Barnett phase theory.Specially for a two-state system,these operators and their commutation relations are discussed in detail.It is conculated that the expectation values and variances of the phase and number operators in the coherent state which is defined in the finite-dimensional space.Finally their equeezing properties are analysed. |
