Hysteresis and synchronization in a two-level system driven by external noise

摘要

The paper discusses a combined effect of periodic and random perturbations on the onset of hysteresis in a generic two-state system. The interplay of both noises is investigated pointing out variations in signal tuning to the external driving force and their influence on the area and shape of the hysteresis. As an extension to former studies relating dynamic hysteresis to stochastic resonance and synchronization of passages in a double well system, in the present work the effect of the field asymmetry on the response of the system is analyzed.
