Anomalous large thermal conductivity has been observed numerically and experimentally in one and two dimensional … debate about the role of conservation of momentum. We introduce a model whose thermal conductivity diverges in dimension 1 … cases, and like $t^{-d/2-1}$ when an on site harmonic potential is present. Consequently thermal conductivity is finite if …
