Thermodynamics "beyond" local equilibrium.
Nonequilibrium thermodynamics has shown its applicability in a wide variety of different situations pertaining to fields such as physics, chemistry, biology, and engineering. As successful as it is, however, its current formulation considers only systems close to equilibrium, those satisfying the so-called local equilibrium hypothesis. Here we show that diffusion processes that occur far away f...
متن کاملBrownian motors: noisy transport far from equilibrium
Transport phenomena in spatially periodic systems far from thermal equilibrium are considered. The main emphasize is put on directed transport in so-called Brownian motors (ratchets), i.e. a dissipative dynamics in the presence of thermal noise and some prototypical perturbation that drives the system out of equilibrium without introducing a priori an obvious bias into one or the other directio...
متن کاملNonequilibrium Brownian Motion beyond the Effective Temperature
The condition of thermal equilibrium simplifies the theoretical treatment of fluctuations as found in the celebrated Einstein's relation between mobility and diffusivity for Brownian motion. Several recent theories relax the hypothesis of thermal equilibrium resulting in at least two main scenarios. With well separated timescales, as in aging glassy systems, equilibrium Fluctuation-Dissipation ...
متن کاملBeyond the Nash Equilibrium Barrier
Nash equilibrium analysis has become the de facto standard for judging the solution quality achieved in systemscomposed of selfish users. This mindset is so pervasive in computer science that even the few papers devoted todirectly analyzing outcomes of dynamic processes in repeated games (e.g., best-response or no-regret learningdynamics) have focused on showing that the perform...
متن کاملPortfolio optimisation beyond semimartingales: shadow prices and fractional Brownian motion∗
While absence of arbitrage in frictionless financial markets requires price processes to be semimartingales, non-semimartingales can be used to model prices in an arbitrage-free way, if proportional transaction costs are taken into account. In this paper, we show, for a class of price processes which are not necessarily semimartingales, the existence of an optimal trading strategy for utility m...
