DYNAMICS OF SQUEEZING FROM GEMERALIZED COHERENT STATES
Salvatore De Martino, Silvio De Siena, Fabrizio Illuminati
Abstract
We extend the definition of generalized coherent states to include the case of time-dependent dispersion. We introduce a suitable operator providing displacement and dynamical rescaling from an arbitrary ground state. As a consequence, squeezing is naturally embedded in this framework, and its dynamics is ruled by the evolution equation for the dispersion. Our construction provides a displacement-operator method to obtain the squeezed states of arbitrary systems.
