From random Poincaré maps to stochastic mixed-mode-oscillation patterns

Nils Berglund, Barbara Gentz, Christian Kuehn

We quantify the effect of Gaussian white noise on fast--slow dynamical systems with one fast and two slow variables, which display mixed-mode oscillations owing to the presence of…

On the noise-induced passage through an unstable periodic orbit II: General case

Nils Berglund, Barbara Gentz

Consider a dynamical system given by a planar differential equation, which exhibits an unstable periodic orbit surrounding a stable periodic orbit. It is known that under random pe…

Sharp estimates for metastable lifetimes in parabolic SPDEs: Kramers' law and beyond

Nils Berglund, Barbara Gentz

We prove a Kramers-type law for metastable transition times for a class of one-dimensional parabolic stochastic partial differential equations (SPDEs) with bistable potential. The…

Hunting French Ducks in a Noisy Environment

Nils Berglund, Barbara Gentz, Christian Kuehn

We consider the effect of Gaussian white noise on fast-slow dynamical systems with one fast and two slow variables, containing a folded-node singularity. In the absence of noise, t…

Anomalous behavior of the Kramers rate at bifurcations in classical field theories

Nils Berglund, Barbara Gentz

We consider a Ginzburg-Landau partial differential equation in a bounded interval, perturbed by weak spatio-temporal noise. As the interval length increases, a transition between a…

The Eyring-Kramers law for potentials with nonquadratic saddles

Nils Berglund, Barbara Gentz

The Eyring-Kramers law describes the mean transition time of an overdamped Brownian particle between local minima in a potential landscape. In the weak-noise limit, the transition…
