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 …

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 …

Topological defects and operators give a far-reaching generalization of symmetries of
quantum fields. An auxiliary topological field theory in one dimension higher than the QFT of …

A bstract We prove a conjectured lower bound on< T__ (x)> ψ in any state ψ of a CFT on
Minkowski space, dubbed the Quantum Null Energy Condition (QNEC). The bound is given …

We consider scalar QED with Nf flavors in AdSD. For D< 4 the theory is strongly-coupled in
the IR. We use the spin 1 spectral representation to compute and efficiently resum the …

We study the holographic duals of four-dimensional field theories with 1-form global
symmetries, both discrete and continuous. Such higher-form global symmetries are …

A bstract We formulate the theory of nonlinear viscoelastic hydrodynamics of anisotropic
crystals in terms of dynamical Goldstone scalars of spontaneously broken translational …

Symmetry-breaking phase transitions are an example of non-equilibrium processes that
require real-time treatment, a major challenge in strongly coupled systems without long-lived …

A bstract The holographic superconductor is one of the most popular models in the context
of applied holography. Despite what its name suggests, it does not describe a …

A bstract We begin the exploration of holographic duals to theories with generalised global
(higher-form) symmetries. In particular, we focus on the case of magnetohydrodynamics …
