Abstract

The (over)completeness of even and odd nonlinear charge coherent states is proved and their generation explored. They are demonstrated to be generalized entangled nonlinear coherent states. A $D$ -algebra realization of the SU $_{f}$ (1,1) generators is given in terms of them. They are shown to exhibit SU $_{f}$ (1,1) squeezing and two-mode $f$ -antibunching for some particular types of $f$ -nonlinearity, but neither one-mode nor two-mode $f$ -squeezing.
