Squeezing property of the states generated by the excitation on the SUq(1,1) even and odd q-coherent states

The squeezing property of states generated by the excitation on the SUq(1,1) even and odd q-coherent states (αq+m|α > qe and αq+m|α >qo) is numerically studied. It is shown that for small q, the state αq+m|α>qe and state αq+m|α>qo can exhibit strong q-squeezing, and as r2 increases the q-squeezing function Δ1e(Δ1o) exhibits a wonderful oscillating phenomenon of increasing-amplitude and increasing-period. As m increases and q decreases, the amplitude of Δ1e(Δ1o) increases greatly. As q decreasing, the period of Δ1e(Δ1o) increases but is independent of m
