Nonlinear deterministic and nonlinear stochastic processes as models in non-equilibrium physics — •Holger Kantz — Max Planck Institute for the Physics of Complex Systems, Dresden, Germany

Due to friction, every macroscopic system eventually enters a rest state unless it is externally driven. Whereas purely constant or periodic driving leads us to deterministic models, additional coupling to a heat bath results in non-equilibrium stochastic processes. This tutorial, to be understood in conjunction with the two other talks given by H. Stark and U. Seiffert, tries to cover the most relevant and most striking aspects of low-dimensional deterministic and stochastic dynamics of driven systems: bifurcations, lack of a superposition principle, self-organisation, and the interpretation as an entropy producing/exporting system.
