Résumé :

k -component q -deformed charge coherent states are constructed, their (over)completeness proved and their generation explored. The q -deformed charge coherent states and the even (odd) q -deformed charge coherent states are the two special cases of them as k becomes 1 and 2, respectively. A D -algebra realization of the SUq (1,1) generators is given in terms of them. Their nonclassical properties are studied and it is shown that for k≥3, they exhibit two-mode q -antibunching, but neither SUq (1,1) squeezing, nor one- or two-mode q -squeezing. © 2005 American Institute of Physics.
