Statistics of transition times, phase diffusion and synchronization in periodically driven bistable systems — •Michael Schindler1, Peter Talkner1, Lukasz Machura1,2, Peter Hänggi1 und Jerzy Łuczka21Theoretical Physics I, Institute of Physics, Augsburg University, Germany — 2Department of Theoretical Physics, Institute of Physics, Silesian University, Poland

The statistics of transitions between the metastable states of a periodically driven bistable Brownian oscillator are investigated on the basis of a two-state description by means of a master equation with time-dependent rates. The results are compared with extensive numerical simulations of the Langevin equation for a sinusoidal driving force. Very good agreement is achieved both for the counting statistics of the number of transitions per period and the residence time distribution of the process in either state. The counting statistics corroborate in a consistent way the interpretation of stochastic resonance as a synchronization phenomenon for a properly defined generalized Rice phase [1].
