Bimodality and hysteresis in systems driven by confined Lévy flights. Dybiec, B. & Gudowska-Nowak, E. New Journal of Physics, 2007. doi abstract bibtex We demonstrate the occurrence of bimodality and dynamical hysteresis in a system describing an overdamped quartic oscillator perturbed by additive white and asymmetric Lévy noise. Investigated estimators of the stationary probability density profiles display not only a turnover from unimodal to bimodal character but also a change in a relative stability of stationary states that depends on the asymmetry parameter of the underlying noise term. When varying the asymmetry parameter cyclically, the system exhibits a hysteresis in the occupation of a chosen stationary state. © IOP Publishing Ltd and Deutsche Physikalische Gesellscnaft.
