Thermal diffusivity and chaos in holographic metals

ORAL

Abstract

We study the thermal diffusivity in holographic models of strange metals. The properties of these metals are related to the properties of gravitational theories in a higher-dimensional curved spacetime. Near generic infra red fixed points of these models, we find that the thermal diffusivity is related to the parameters characterising many-body chaos. This is true independently of the charge density, magnetic field, or periodic potential strength, and is a consequence of a universal feature of certain black hole horizons.
