SUMMARY:Scaling down the laws of thermodynamics\, Physics Department C
 olloquium\, Christopher Jarzynski\, UMD
DESCRIPTION:Thermodynamics provides a robust conceptual framework and 
 set of laws that govern the exchange of energy and matter. Although th
 ese laws were originally articulated for macroscopic objects\, nanosca
 le systems also exhibit “thermodynamic¬-like” behavior – for in
 stance\, biomolecular motors convert chemical fuel into mechanical wor
 k\, and single molecules exhibit hysteresis when manipulated using opt
 ical tweezers. To what extent can the laws of thermodynamics be scaled
  down to apply to individual microscopic systems\, and what new featur
 es emerge at the nanoscale? I will describe some of the challenges and
  recent progress – both theoretical and experimental – associated 
 with addressing these questions.  Along the way\, my talk will touch o
 n non-equilibrium fluctuations\, “violations” of the second law\, 
 the thermodynamic arrow of time\, nanoscale feedback control\, strong 
 system-environment coupling\, and quantum thermodynamics.
