Planckian dissipation

Abstract: What does everyday copper, high temperature superconductors, magic angle graphene, black holes and the quark gluon plasma have in common? All of them, in some regime, are controlled by a `Planckian’ transport timescale made up from fundamental constants and the temperature: tau ~ hbar/(k T). I will review recent and not-so-recent appearances of this timescale across physics, and will discuss whether the ubiquitous appearance of this timescale is a coincidence or potentially indicative of a deep principle in quantum statistical mechanics.
