Abstract: The macroscopic fluctuation theory, proposed in collaboration with L. Bertini. A. De Sole, D. Gabrielli and C. Landim to study diffusive systems out of equilibrium, developed over the last decade into a powerful tool to solve concrete problems. After discussing the basic ideas I will illustrate some applications among which the existence of phase transitions in the behaviour of fluctuations. Of special interest are the fluctuations of the current in stationary states. New variational principles appear in the thermodynamics of non-equilibrium stationary states.
