Title: "Records of Entropy Production at the Nanoscale"

Speaker: Edgar Roldan, Max Planck Institute for the Physics of Complex 
Systems, Dresden, Germany

Abstract:
The laws of thermodynamics can be extended to the nanoscale, where 
fluxes are fluctuating quantities. Little is known about extreme-value 
statistics of thermodynamic fluxes characterising the most extreme 
deviations from the average behaviours. Using Martingale theory, we 
study statistics of the negative records of stochastic entropy 
production in nonequilibrium steady states, and derive universal 
inequalities for such distributions of records. Furthermore, we explore 
the implications of our results in two non-equilibrium nanoscopic 
systems: single-electron transistors and molecular motors. We report on 
the experimental measurement of stochastic entropy production and of 
records of negative entropy in a metallic double dot under a constant 
external DC bias. Experimental results on the double dot confirm our 
theory and reveal a novel bound for the maximal heat that a mesoscopic 
system can absorb from its environment. We also explore our results in 
active biological processes and find predictions for the maximal 
excursion of a molecular motor against the direction of an external force.
