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.
