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 …

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 discovery of correlated states and superconductivity in magic-angle twisted bilayer
graphene (MATBG) established a new platform to explore interaction-driven and topological …

Magic-angle (θ= 1.0 5°) twisted bilayer graphene (MATBG) has shown two seemingly
contradictory characters: the localization and quantum-dot-like behavior in STM …

Abstract Fractional Chern insulators (FCIs) are lattice analogues of fractional quantum Hall
states that may provide a new avenue towards manipulating non-Abelian excitations. Early …

In a flat band superconductor, the charge carriers' group velocity v F is extremely slow.
Superconductivity therein is particularly intriguing, being related to the long-standing …

Moiré quantum matter has emerged as a materials platform in which correlated and
topological phases can be explored with unprecedented control. Among them, magic-angle …

Recent experiments on rhombohedral pentalayer graphene with a substrate-induced moiré
potential have identified both Chern insulators and fractional quantum Hall states at zero …

In condensed-matter systems, higher temperatures typically disfavour ordered phases,
leading to an upper critical temperature for magnetism, superconductivity and other …

The interaction between electrons in graphene under high magnetic fields drives the
formation of a rich set of quantum Hall ferromagnetic (QHFM) phases with broken spin or …
