Creating Coherent States in a Mesoscopic Josephson Junction
Shao Bin, Jian Zou, Qian-Shu Li · Modern Physics Letters B · 1998
We examine a system of mesoscopic Josephson junction driven by classical field and solve the time-dependent Schrödinger equation of the system with the help of the time-dependent invariant of the Hamiltonian operator. We show that the state of the system can evolve a pure coherent state when the junction is prepared initially in its ground state.
