The Colloquium reviews recent progress in the effective description of strongly correlated
phases of matter with spontaneously broken translations, such as charge density waves or …

High-T c cuprate strange metals are characterized by a DC resistivity that scales linearly with
T from the onset of superconductivity to the crystal melting temperature, characterized by a …

A bstract Cosmological phase transitions can proceed via the nucleation of bubbles that
subsequently expand and collide. The resulting gravitational wave spectrum depends …

We show that the correlator of three large charge operators with minimal scaling dimension
can be computed semiclassically in conformal field theories (CFTs) with a U (1) symmetry for …

A bstract We study the fermionic spectral density in a strongly correlated quantum system
described by a gravity dual. In the presence of periodically modulated chemical potential …

Strongly-correlated states of matter present a serious theoretical challenge, as perturbation
theory typically fails to describe them. High critical temperature (Tc) superconductors [1] …

A bstract We explore the state of matter characterized by the charged timelike vector order
parameter. We employ holographic duality in order to construct such a state and study its …

General relativity can describe various gravitational systems of astrophysical relevance, like
black holes and neutron stars, or even strongly coupled systems through the holographic …

A bstract We study the charge density response in holographic models with explicit trans-
lation symmetry breaking which is relevant in IR. In particular, we focus on Q-lattices and the …

Today's novel materials can display many interesting phases. Two-dimensional materials
with strong electron-electron interactions allow the electrons to enter a hydrodynamic regime …
