Anomalous fluctuations for a perturbed Hamiltonian system with
exponential interactions [PDF]
Cedric Bernardin, P. GonçalvesA one-dimensional Hamiltonian system with exponential interactions perturbed by a conservative noise is considered. It is proved that energy superdiffuses and upper and lower bounds describing this anomalous diffusion are obtainedView original: http://arxiv.org/abs/1205.1879
