Fluctuating currents in stochastic thermodynamics: Large deviations techniques and nonequilibrium response theory
Dr. Bernhard Altaner (University Luxemburg)

Stochastic Thermodynamics provides a modern framework for the treatment of fluctuating systems in nonequilibrium environments. From a thermodynamic perspective, we are interested in the statistics of the physical currents (of heat, particles etc.) that flow through a system, and their response to external perturbations.
In this talk, I will provide an introduction to Markovian stochastic Thermodynamics, show how current statistics (mean currents, diffusivities) can be calculated analytically and report on a novel nonequilibrium fluctuation-dissipation relation for locally perturbed currents.
