PHASE TRANSITIONS WITH QUENCHED DISORDER: UNIVERSALITY AND NON-SELFAVERAGING.
Université Pierre et Marie CurieLong standing problem of the nature of the phase transitions in weakly disordered Ising-like statistical systems  is considered from the point of view of the recent developments in the replica method . In particular, non-perturbative  and non-selfaveraging  phenomena in the critical point are considered, as well as the possibility of the universal probability distribution function for non-self averaging free energy critical fluctuations is discussed .
