Deterministic force-free resonant activation
Karol Capała, Bartłomiej Dybiec
Combined action of noise and deterministic force in dynamical systems can induce resonant effects. Here, we demonstrate a minimal, deterministic-force-free, setup allowing for occu…
Lévy noise-driven escape from arctan potential wells
Karol Capala, Amin Padash, Aleksei V. Chechkin +3
The escape from a potential well is an archetypal problem in the study of stochastic dynamical systems, representing real-world situations from chemical reactions to leaving an est…
Underdamped, anomalous kinetics in double-well potentials
Karol Capała, Bartłomiej Dybiec
The noise driven motion in a bistable potential acts as the archetypal model of various physical phenomena. Here, we contrast the overdamped dynamics with the full (underdamped) dy…
Nonlinear friction in underdamped anharmonic stochastic oscillators
Karol Capała, Bartłomiej Dybiec, Ewa Gudowska-Nowak
Stationary states of overdamped anharmonic stochastic oscillators driven by Lévy noise are typically multimodal. The very same situation is recorded for an underdamped Lévy noise d…
