Abstract

A common problem of simulations using Drummond-Gardiner positive P-representation^[1] was large excursions from the average,^[2] which we call divergences. However, some simulations were successful,^[3] confirming the advantage of Drummond-Gardiner positive P-function.^[1] In this paper, we report a simulation of the parametric oscillator dynamics in the sub-threshold regime,^[2] in which the problems of divergences have been eliminated, and in the above threshold regime, where tunneling between two states occurs.^[3]
