| Abstract: | In non-equilibrium there is an enormous variety of phenomena so we cannot hope to formulate a unique theory having a generality comparable to classical thermodynamics. We have to restrict to subclasses of problems. Diffusion is a phenomenon almost ubiquitous and in recent years considerable progress in its understanding has been obtained. One difficulty is to define suitable thermodynamic functionals in far from equilibrium situations. Large fluctuations have offered a way out as large deviation rates provide genuine thermodynamic functionals whose singularities describe new phase transitions some of which can take place only out of equilibrium.
