摘　　要：Phase properties of the even and odd circular states are studied within the Hermitian phase formalism of Pegg and Barnett. Exact analytical formulas for the distribution function and the variance of the phase operator are obtained and used to examine whether or not the even and odd circular states exhibit photon-number squeezing and phase squeezing.Phase properties of the even and odd circular states are studied within the Hermitian phase formalism of Pegg and Barnett.
