Generic interacting many-body quantum systems are believed to behave as classical fluids
on long time and length scales. Due to rapid progress in growing exceptionally pure crystals …

The “flow” of electric currents and heat in standard metals is diffusive with electronic motion
randomized by impurities. However, for ultraclean metals, electrons can flow like water with …

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 …

In electrically conductive solids, the Wiedemann-Franz law requires the electronic
contribution to thermal conductivity to be proportional to electrical conductivity. Violations of …

We compute the thermodynamic properties of the Sachdev-Ye-Kitaev (SYK) models of
fermions with a conserved fermion number Q. We extend a previously proposed Schwarzian …

Electron transport is conventionally determined by the momentum-relaxing scattering of
electrons by the host solid and its excitations. Hydrodynamic fluid flow through channels, in …

In stark contrast to ordinary metals, in materials in which electrons strongly interact with each
other or with phonons, electron transport is thought to resemble the flow of viscous fluids …

The anomalous transport of important materials such as high-temperature superconductors
and other 'bad metals' is not well understood theoretically. In an incoherent metal, transport …

A bstract We introduce a new framework for constructing black hole solutions that are
holographically dual to strongly coupled field theories with explicitly broken translation …

A bstract An analytic expression for the DC electrical conductivity in terms of black hole
horizon data was recently obtained for a class of holographic black holes exhibiting …
