In multistable dynamical systems driven by weak Gaussian noise, transitions between
competing states are often assumed to pass via a saddle on the separating basin boundary …

We present a perturbation approach to calculate the short-time propagator, or transition
density, of the one-dimensional Fokker-Planck equation, to in principle arbitrary order in the …

Metastable states appear as long-lived intermediate states in various natural transport
phenomena which are governed by energy landscapes. Moreover, they dominate a system's …
