Abstract: I will start by discussing some of the main challenges that one faces when trying to formulate a nonequilibrium thermodynamics of complex systems. I will then discuss how to use stochastic thermodynamics to make progress in that direction by considering systems which display a macroscopic limit (e.g. chemical reaction networks, nonlinear electric circuits and Potts models). I will discuss in particular how an emergent second law can be used to bound the rate function of nonequilibrium steady states (NESS) using the macroscopic heat [1]. I will also describe a novel linear response regime at the level of NESS rate functions [2] and show that it saturates these bounds. If time permits, I will briefly describe some recent results on nonequilibrium phase transitions [3,4,5].
