Stochastic thermodynamics


Stochastic thermodynamics has become a comprehensive framework to describe driven (mesoscopic) systems governed by stochastic dynamics. The key concepts are the identification of fluctuating work, heat, and entropy. We use these concepts in our research (e.g., on active matter and coarse-graining) as the theoretical foundations to describe driven matter.

Transport coefficients

One area in which stochastic thermodynamics has contributed is the linear response theory for small perturbations of non-equilibrium steady states (in contrast to the conventional perturbation of equilibrium states). Based on these results we develop new algorithms and methods to determine transport coefficients from numerical simulations both close and far from thermal equilibrium.
