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 …

Superconductivity is a remarkably widespread phenomenon that is observed in most metals
cooled to very low temperatures. The ubiquity of such conventional superconductors, and …

Near the boundary between ordered and disordered quantum phases, several experiments
have demonstrated metallic behaviour that defies the Landau Fermi paradigm,,,–. In moiré …

The appearance of the Planckian time τ Pl= ℏ/k BT is reviewed in both conventional and
unconventional metals. A pedagogical discussion of the various different timescales …

The flat bands of magic-angle twisted bilayer graphene (MATBG) host strongly correlated
electronic phases such as correlated insulators,,,–, superconductors,,,–and a strange metal …

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 …

The perfectly linear temperature dependence of the electrical resistivity observed as T→ 0 in
a variety of metals close to a quantum critical point,,–is a major puzzle of condensed-matter …

S trange-metal behavior has been observed in materials ranging from high-temperature
superconductors to heavy fermion metals. In conventional metals, current is carried by …

A variety of 'strange metals' exhibit resistivity that decreases linearly with temperature as the
temperature decreases to zero,–, in contrast to conventional metals where resistivity …

Strange metals possess highly unconventional electrical properties, such as a linear-in-
temperature resistivity,,,,–, an inverse Hall angle that varies as temperature squared,–and a …
