Even and odd q-deformed charge coherent states and their nonclassical properties

Even and odd q-deformed charge coherent states are constructed, their (over)completeness proved and their generation explored. A D-algebra realization of the SUq(1,1) generators is given in terms of them. They are shown to exhibit SUq(1,1) squeezing and two-mode q-antibunching, but neither one-mode, nor two-mode q-squeezing
