I discuss the impact of gauge-gravity duality on our understanding of two classes of systems:
conformal quantum matter and compressible quantum matter. The first conformal class …

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 …

General scaling arguments, and the behavior of the thermal entropy density, are shown to
lead to an infrared metric holographically representing a compressible state with hidden …

In these lecture notes we review some recent attempts in searching for non-Fermi liquids
and novel quantum phase transitions in holographic systems using gauge/gravity duality …

A bstract We present an analytic solution of a charged black hole with hyperscaling violating
factor in an Einstein-Maxwell-Dilaton model where the scalar potential is key to the …

A bstract Gauge/gravity duality applied to strongly interacting systems at finite density
predicts a universal intermediate energy phase to which we refer as a semi-local quantum …

We use gauge-gravity duality to model the crossover from a conformal critical point to a
confining Fermi liquid, driven by a change in fermion density. The short-distance conformal …

A bstract Certain holographic states of matter with a global U (1) symmetry support a sound
mode at zero temperature, caused neither by spontaneous symmetry breaking of the global …

We compute the contribution to the conductivity from holographic Fermi surfaces obtained
from probe fermions in an AdS charged black hole. This requires calculating a certain part of …

A bstract We study lattice effects in strongly coupled systems of fermions at a finite density
described by a holographic dual consisting of fermions in Anti-de-Sitter space in the …
