Squeezing properties of q -deformed oscillator
Guo Guang-Can, Liang Jiu-Qing · Acta Physica Sinica (Overseas Edition) · 1994
The q -coherent states are indeed minimum uncertainty states for corresponding q -deformed operators. The time evolution of q -coherent states are given by introducing the q -boson Hamiltonian analogous to the one for normal bosons. It is shown that initially prepared q -coherent states are no longer the eigenstates of q -annihilation operator during time evolution and eventually become squeezing states. The squeezing properties are studied numerically.
