Phys. Rev. Lett. 89, 200601 (2002) [4 pages]Anomalous Heat Conduction in One-Dimensional Momentum-Conserving SystemsReceived 16 May 2002; published 24 October 2002 We show that for one-dimensional fluids the thermal conductivity generically diverges with system size L as L1/3, as a result of momentum conservation. Our results are consistent with the largest-scale numerical studies of two-component hard-particle systems. We suggest explanations for the apparent disagreement with studies on Fermi-Pasta-Ulam chains. © 2002 The American Physical Society URL:
