| Description |
Fourier's law of heat conduction predicts that heat propagation in a solid is diffusive. Fourier's law is a phenomenological macroscopic law and its derivation for a microscopic model with Hamiltonian dynamics is an open problem. A large number of studies over the last few decades suggest that this law is in fact not generally valid in low-dimensional systems. I will discuss what we know about this problem and some of the interesting open problems in this field. |
