FPU chains (an array of weights chained to their neighbors via springs) are used to model 1-dimensional crystals. Depending on the interaction potential considered, anomalous heat transport is expected. Based on the results of Lukkarinen and Spohn, we study the emergence of the fractional heat equation with laplacian of order 4/5 for FPU chains with quartic interaction potentials.
