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 -algebra realization of the SU(1,1) generators is given in terms of them. They are shown to exhibit SU(1,1) squeezing and two-mode -antibunching for some particular types of -nonlinearity, but neither one-mode nor two-mode -squeezing.
