The physics of small systems: From energy to information Authors Fèlix Ritort Departament de Física de la Matèria Condensada University of Barcelona Keywords: Brownian motion, Nyquist noise, stochastic thermodynamics, Maxwell demon, glassy systems Abstract The focus of this review is the recent developments in the non-equilibrium physics of small systems. Special emphasis is placed on single-molecule experiments and their contribution to expanding our current understanding of fundamental concepts, such as temperature, energy, entropy, and information.
