Abstract
We investigate the system of stochastic differential equation which describe the time phase evolution of a two-junction quantum interferometer in the presence of white noises. The effective algorithms of expansion of special Fokker-Plank equation with small and large parameters are proved. The estimations of approximations are obtained. © 2009 World Scientific Publishing Co. Pte. Ltd.File in questo prodotto:
