On q-squeezed states
A. I. Solomon, Jacob Katriel
Abstract
The authors present the results of an analysis of the squeezing of components of the (conventional) electromagnetic field in quantum group analogues of the Heisenberg-Weyl (HW) coherent state and SU(1,1) squeezed state. They find that squeezing occurs for all finite-q values not equal to unity in the HW q-coherent state, in contrast to the usual case; and also in the SU q (1,1) case, although here less than in the usual (q=1) SU(1,1) squeezed state.
