KRZYSZTOF GAWEDZKI
Professor, Ecole Normale Superieur, Lyon $$ Krzysztof Gawedzki is a mathematical and theoretical physicist who has worked at Warsaw University, Institut des Hautes Etudes Scientifique near Paris and, most recently, at Ecole Normale Superieur in Lyon. His interests cover a variety of subjects: quantum field theory, turbulent transport, non-equilibrium statistical mechanics, or topological insulators. Presently, he is a researcher-emeritus at ENS in Lyon.

Abstract:
Recent years have brought a considerable progress in the understanding of the role played by fluctuations in the non-equilibrium behavior of mesoscopic systems: colloidal particles, polymers in flows, molecular motors, and alike. A theory governing such fluctuations, known under the name of Stochastic Thermodynamics, encompasses several general results extending the laws of thermodynamics to fluctuation dominated situations. For illustration, I shall concentrate on the refinement of the Second Law for processes driven on time scales comparable or shorter than the relaxation time of fluctuations. For classical systems such a refinement is related to the optimal mass transport problem that goes back to the works of Monge and Kantorovich in previous centuries. It provides a short-time improvement of the Landauer principle about memory erasure. An attempt to carry over such results to quantum systems will be also described.
