Towards a theory of strange quantum metals
Senthil Todadri, Massachusetts Institute of Technology,

Electrons in a conventional metal are described by Landau's celebrated theory of Fermi liquids. In the last few decades a growing number of metals have been discovered that defy a description in terms of Fermi liquid theory. Prominently, such strange metals'  appear as parent phases out of which phenomena such as high temperature superconductivity develop. However their theoretical understanding has mostly remained mysterious.  In this talk, I will discuss, in great generality, some properties of  strange  metals' in an ideal clean system.  I will discuss general constraints on the emergent low energy symmetries  of any such strange metal.

I will show how these model-independent considerations lead to concrete experimental predictions about a class of strange metals. Time permitting, I will discuss the utility of a focus on the emergent symmetries to reliably extract some physical properties of certain models of strange metals.  All attendees must have a valid Caltech ID
