Properties of Amplitude N th-power Squeezing of Even and Odd qs-Coherent States |
| |
Abstract: | By using the numerical method, the properties of the amplitude Nth-power squeezing of the even and odd qs-coherent states are studied. It is shown that these even and odd qs-coherent states are very different from the usual even and odd states. It is found that the Nth-power (N=2m+1,m=0,1,2,…) squeezing appears for both the even and odd qs-coherent states in some ranges of the parameters q,s and r. The smaller the q and s,the larger the difference between the even and odd qs-coherent states and the usual even and odd coherent states. |
