DESCRIPTION:Zoom link: https://maths-cam-ac-uk.zoom.us/j/94018037756\n\nOv
 er last decades\, substantial progress has been made towards the elaborati
 on of a thermodynamic theory for systems on a mesoscopic scale\, better kn
 own as stochastic thermodynamics. On such a scale\, systems can be describ
 ed by a large diversity of stochastic processes\, including master equatio
 ns\, stochastic differential equations for individual Brownian particles o
 r fluctuating hydrodynamics for continuous field variables. In this talk\,
  I will present a recent\, top-down approach to stochastic thermodynamics 
 -the eLEH stochastic thermodynamics- particularly suited for systems descr
 ibed at the fluctuating hydrodynamics level of description. This approach 
 can be applied to various physical phenomena: simple diffusive transport [
 1]\, coupled transport (thermodiffusion) [2]\, (non-)linear chemical react
 ions [3] and solutions of Brownian particles [4]. Going through analytical
  and numerical study of different toy-models for these phenomena\, I will 
 show how general properties of fluctuations of thermodynamic quantities ca
 n be drawn with this approach.\n\n[1] Y. De Decker\, A. Garcia Cantú Ros\
