Squeezed states and the Franck-Condon overlap
L. Sandoval, Manuel Martín, Juan Francisco Rivas-Silva, Alberto José Palma · Physical Review A · 1992
A simple and direct approach to studying squeezed states is proposed. It is based on treating the corresponding differential equations and their solutions directly on the Fock-Bargmann space. The method is exemplified by giving quite general solutions to the case of amplitude-squared squeezed states. We show the importance of this approach by deriving the overlap between these solutions and connecting them with the overlap integral associated with the Franck-Condon principle.
