Quantum Statistical Properties of Even and Odd qs-Coherent States

In this paper, we use the numerical method to study the influences of q and s deformations on the quantum statistical Properties of even and odd qs-coherent states. It is shown that nonclassical properties of the even and odd qs-coherent states are very different from those of the usual even and odd coherent states. It is found that squeezing and antibunching effect appear for both even and odd qs-coherent states in some range of the parameters q, s and r. The smaller the q (q < 1) and s are, the.Jarger the difference between the even and odd qs-coherent states and the usual even and odd coherent states is.
