This is a review of the Sachdev-Ye-Kitaev (SYK) model of compressible quantum many-
body systems without quasiparticle excitations, and its connections to various theoretical …

In traditional metals, the temperature (T) dependence of electrical resistivity vanishes at low
or high T, albeit for different reasons. Here, we review a class of materials, known as …

A comprehensive overview of holographic methods in quantum matter, written by pioneers
in the field. This book, written by pioneers in the field, offers a comprehensive overview of …

We examine models of fermions with infinite-range interactions that realize non-Fermi
liquids with a continuously variable U (1) charge density Q and a nonzero entropy density S …

Insulators occur in more than one guise; a recent finding was a class of topological
insulators, which host a conducting surface juxtaposed with an insulating bulk. Here, we …

Studies of the electromagnetic response of various classes of correlated electron materials
including transition-metal oxides, organic and molecular conductors, intermetallic …

These notes are loosely based on lectures given at the CERN Winter School on
Supergravity, Strings and Gauge theories, February 2009, and at the IPM String School in …

Could it be that the matter from the electrons in high Tc superconductors is of a radically new
kind that may be called" many body entangled compressible quantum matter"? Much of this …

We highlight the progress, current status, and open challenges of QCD-driven physics, in
theory and in experiment. We discuss how the strong interaction is intimately connected to a …

The IR dynamics of effective holographic theories capturing the interplay between charge
density and the leading relevant scalar operator at strong coupling are analyzed. Such …
