Lévy noise induced transitions and enhanced stability in a birhythmic van der Pol system
arXiv:1912.11244 · doi:10.1140/epjb/e2019-100029-x
Abstract
This work describes the effects of Lévy noise on a birhythmic van der Pol like oscillator. Numerical simulations demonstrate that the noise induced escapes from an attractor to another are not markedly different from escapes between stable points in an ordinary potential, albeit the attractors are separated by a barrier of a quasi (or pseudo) potential. However, some differences appear, and are more pronounced when the Lévy distribution index is close to two.
