Anomalous Transport in the Fermi-Pasta-Ulam-Tsingou Model: A Review and Open Problems

Abstract This review provides an up-to-date account of energy transport in Fermi-Pasta-Ulam-Tsingou (FPUT) chains, a key testbed for nonequilibrium statistical physics. We discuss the transition from the historical puzzle of thermalization to the discovery of anomalous heat trans...
