SUMMARY:Superdiffusion transition for a noisy harmonic chain subject to a 
 magnetic field - Gaëtan  Cane (Université de Nice Sophia Antipolis)

DESCRIPTION:Understanding the diffusive or superdiffusive behavior of the 
 energy in classical physical systems is challenging because of the non-lin
 earity of the interactions between the particles. A way to reduce the diff
 iculty is to replace the nonlinearity by a stochastic noise. In this prese
 ntation I will consider a noisy harmonic chain subjected to a magnetic fie
 ld. We will see that according to the intensity of the magnetic field\, th
 e superdiffusive nature of the system changes.
