This paper is devoted to the study of the probability distribution of fluctuations of physical observables in a thermodynamical system, either in equilibrium or out of equilibrium. Interestingly, even relatively simple systems, exhibit a complex pattern of fluctuations, characterized by non-analyticities of their probability distribution. Singularities in thermodynamics are known to be associated to phase transitions. In the problem at hand, the non-analyticities of the probability distribution can be interpreted as due to a peculiar phase transition occurring at the level of fluctuating quantities.

This paper addresses the problem of percolation effects in phase ordering kinetics. Phase ordering is the phenomenon whereby a initially disordered binary systems evolve towards an ordered state. Typical examples are the formation of magnetic domains in a material quenched below the Curie temperature, or the demixing of a binary liquid -- oil and vinegar to mention a familiar one. It has been recently discovered that the largest domain present in the system at a given observation time (magnetic domain or oil bubble in the previous examples) exhibits the fractal properties of random percolation.
