Topological semimetals (TSMs) are characterized by bulk band crossings in their electronic
structures, which are expected to give rise to gapless electronic excitations and topological …

The physics of quantum materials is dictated by many-body interactions and mathematical
concepts such as symmetry and topology that have transformed our understanding of matter …

Weyl semimetals are crystalline solids that host emergent relativistic Weyl fermions and
have characteristic surface Fermi-arcs in their electronic structure. Weyl semimetals with …

Superconductivity can occur under conditions approaching broken-symmetry parent states.
In bilayer graphene, the twisting of one layer with respect to the other at 'magic'twist angles …

Weyl and Dirac semimetals are three-dimensional phases of matter with gapless electronic
excitations that are protected by topology and symmetry. As three-dimensional analogs of …

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 …

Electronic flat-band materials host quantum states characterized by a quenched kinetic
energy. These flat bands are often conducive to enhanced electron correlation effects and …

Complex oxides with 4 d and 5 d transition-metal ions recently emerged as a new paradigm
in correlated electron physics, due to the interplay between spin–orbit coupling and electron …

Weyl fermions were originally proposed as massless Dirac fermions in relativistic quantum
field theory. In solids, Weyl fermions often appear when either time-reversal symmetry or …

The topological semimetal is a new, theoretically predicted and experimentally discovered,
topological state of matter. In one of its several realizations, the topological semimetal hosts …
