Query: 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 SU$_q$(1,1) generators is given in terms of them. They are
shown to exhibit SU$_q$(1,1) squeezing and two-mode $q$-antibunching, but
neither one-mode, nor two-mode $q$-squeezing.
