Abstract
We construct explicitly even and odd qs-coherent states ( qs-CSs), which are proved to form a representation of the quantum Heisenberg-Weyl algebra, and use the numerical method to study the influences of q and s deformations on photon-statistical properties of even and odd qs-CSs. It is shown that nonclassical properties of the even and odd qs-CSs are very different from those of the usual even and odd coherent states (CSs). It is found that the squeezing and antibunching effects appear for both even and odd qs-CSs in some range of the parameters q, s and r. The smaller the q ( q < 1) and s, the larger the difference between the even and odd qs-CSs and the usual even and odd CSs.
