Non-Fermi liquids and the lattice — •Sean Hartnoll — Stanford University

Non-Fermi liquids are electronic systems with strong electronic interactions. For example, the electrons may be quantum critical. Therefore, the electrons are expected to thermalize quickly. However, heat must also be able to leave the electronic degrees of freedom -- for example, this will happen by Joule heating upon applying a current. In a metal Joule heating goes via the lattice degrees of freedom. I will explain a new formalism for computing the timescales over which the electronic and lattice degrees of freedom thermalize each other in a non-Fermi liquid.
