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 …

Topological quantum materials (TQMs) have symmetry-protected band structures with useful
electronic properties that have applications in information, sensing, energy and other …

Graphene is very popular because of its many fascinating properties, but its lack of an
electronic bandgap has stimulated the search for 2D materials with semiconducting …

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 …

We present an open-source software package WannierTools, a tool for investigation of novel
topological materials. This code works in the tight-binding framework, which can be …

Quantum materials hosting Weyl fermions have opened a new era of research in condensed
matter physics. First proposed in 1929 in the context of particle physics, Weyl fermions have …

Topological insulators and topological semimetals are both new classes of quantum
materials, which are characterized by surface states induced by the topology of the bulk …

In recent years, transition metal dichalcogenides (TMDs) have garnered great interest as
topological materials. In particular, monolayers of centrosymmetric β-phase TMDs have …

Noncentrosymmetric metals are anticipated to exhibit a dc photocurrent in the nonlinear
optical response caused by the Berry curvature dipole in momentum space. Weyl …

The theoretical proposal of chiral fermions in topological semimetals has led to a significant
effort towards their experimental realization. In particular, the Fermi surfaces of chiral …
