Kramers-like problem for Lévy flights
A noise induced escape of a particle is one of the archetypal problemsin stochastic dynamics. Among others, it was studied by H. A. Kramersin the case of the Gaussian white noise in overdamped (largeviscosity) and underdamped (small viscosity) regimes. In theoverdamped regime, the obtained formula for the reaction rate can beinterpreted as the Arrhenius equation. Therefore, the stochasticmotion in the double-well potential can be used as an effective modelof chemical reactions.
Since then, the noise induced escape of a particle was intensivelystudied in the overdamped and underdamped regimes as well as inquantum setups. I will present extension of problem of the transitionrates in a double-well potential to the case of Lévy noises in bothover- and underdamped regime.
The seminar will be conducted on Zoom
