Abstract:

Studies of non-equilibrium fluctuations have held a center stage during the
past few decades of the development of non-equilibrium statistical mechanics.


Indeed, macroscopic fluctuations are supposed to display some universal behaviour, regardless of the precise microscopic dynamics of the process
under study.


In this talk, we shall consider a few examples of non-equilibrium fluctuations: the particle current in an interacting particle system, the diffusion of a tracer in a one-dimensional gas of  particles with excluded mutual passage and the melting of an Ising quadrant.
These different problems will be analyzed quantitatively using the Macroscopic Fluctuation Theory
