KERR INTERACTION WITH DISPLACED AND SQUEEZED FOCK STATES

Displaced and squeezed Fock states have recently been thoroughly investigated. Application of these states as the input of a Kerr nonlinear medium reveals many nonclassical effects. We solve this problem analytically and demonstrate results by numerical examples. We introduce a phase distribution for the antinormal quasidistribution scrA and show that the phase of the new states can be sharply localized at some values. This happens when revivals appear in the field. If the states are shifted by a reference wave, photon-number distributions clearly detect the structure of scrA. Damping of the new states is briefly discussed. © 1990 The American Physical Society.
