Piecewise-smooth dynamical systems have attracted a lot of interest in the last decade. Whereas deterministic models have been studied intensely, their stochastic counterpart is still in its infancy. Systems with dry friction subjected to stochastic perturbations are prominent examples of piecewise-smooth stochastic systems. There are only a few cases known, where exact results can be obtained.
In the first part of my talk I will give a short introduction of concepts and methods from statistical physics, e.g. the Langevin equation and the Fokker-Planck equation. Then I will talk about dry friction models subjected to Gaussian white noise. Finally I will present some recent results for a dry friction model and coloured (exponentially correlated) noise.
