The propagator formulation of the degenerate parametric oscillator
Abstract
After systematically deriving general expressions for a twotime correlation function and the photon number distribution in terms of the Qfunction, we analyze the squeezing spectrum and the photon number distribution of the signal mode produced by a degenerate parametric oscillator operating below threshold. The timedependent Qfunction is obtained by solving the pertinent FokkerPlanck equation applying the method of evaluating the propagator discussed in J. Math. Phys. 33 (1992) 2179.
