Carina-Mihaela Raportaru from the National Institute for Physics and Nuclear Engineering - NIPNE, Bucharest, Romania held a seminar talk entitled "Noise-driven transitions in nonlinear lattices".

Abstract of the talk:

The classical Fermi-Pasta-Ulam problem will be considered in the context of stochastic stability to show that spatially periodic states that are Lyapunov stable are unstable with respect to stochastic perturbations.
