Abstract

The problem of stationary heat transport in the Fermi-Pasta-Ulam chain is numerically studied showing that the conductivity diverges in the thermodynamic limit. Simulations were performed with time-reversible thermostats, both for small and large temperature gradients. In the latter case, fluctuations of the heat current are shown to be in agreement with the recent conjectures of Gallavotti and Cohen.
