Momentum Conserving Model with Anomalous Thermal Conductivity in Low Dimensional Systems
Momentum Conserving Model with Anomalous Thermal Conductivity in Low Dimensional Systems
Anomalous large thermal conductivity has been observed numerically and experimentally in one- and two-dimensional systems. There is an open debate about the role of conservation of momentum. We introduce a model whose thermal conductivity diverges in dimensions 1 and 2 if momentum is conserved, while it remains finite in dimension …
