DESCRIPTION:Stochastic thermodynamics has uncovered some fundamental laws 
 that govern the fluctuations of mesoscale systems\, even far from thermal 
 equilibrium. It bridges the gap between macroscopic thermodynamics and the
  deterministic microscopic laws\, and provides a way to describe the effic
 iency and performance of mesoscale machines. A central quantity in this fr
 amework is the entropy production\, which explicitly measures the time-rev
 ersal symmetry breaking of fluctuating dynamics\, and\, under certain assu
 mptions\, can be related to the heat dissipation. However\, many results o
 f stochastic thermodynamics\, including the close connection between entro
 py and energy\, break down if there is no clear time-scale separation betw
 een "the bath" and "the system". In this talk\, I will present some insigh
 ts into the fluctuations and thermodynamic notions of nonequilibrium syste
 ms that do not fall into the usual paradigm of stochastic thermodynamics.
