Quantum treatment of the time-dependent coupled oscillators
M. Sebawe Abdalla · Journal of Physics A Mathematical and General · 1996
The Hamiltonian for a system of two coupled oscillators with time-dependent coupling parameter and the phase pump is considered. The wavefunction in Schrödinger picture and the Green function are calculated. The squeezing phenomena as well as the Glauber second-order correlation function is discussed. Statistical investigation for the quasi-probability distribution function (P-representation, W-Wigner and Q-functions) are given.
