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.

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
