Abstract

An effective bosonic Hamiltonian describing the interaction of a mesoscopic Josephson junction with a quantized radiation field is studied. We find that when the field was initially prepared in a coherent state and the junction initially in its lowest energy level state, the state of the coupled system may evolve into a squeezed state. Our results show that as time evolves both the field and Josephson junction subsystems can exhibit nonclassical behaviour.
