Abstract

In this paper, the photon subtracted generalized coherent states for nonharmonic oscillators in a nonlinear Kerr medium have been introduced. Then, the number- phase Winger function of the introduced states was investigated. The Wigner function was negative in some regions which showed the nonclassical signature of these states. Finally, the phase properties of these states were discussed by using Pegg-Barnett phase distribution function formalism which showed that this distribution function has higher and sharper peaks for smaller  and thus, it was more localized with respect to . Finally, number- phase squeezing and number- phase entropy uncertainty relation for these states were investigated. By studing the number- phase squeezing can be concluded that these states are nonclassical signature.
