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 …

Light–matter interaction in 2D and topological materials provides a fascinating control knob
for inducing emergent, non-equilibrium properties and achieving new functionalities in the …

Topological quantum chemistry and symmetry-based indicators have facilitated large-scale
searches for materials with topological properties at the Fermi energy (EF). We report the …

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 electronic materials such as bismuth selenide, tantalum arsenide and sodium
bismuthide show unconventional linear response in the bulk, as well as anomalous gapless …

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 …

Semimetals are being explored for their unique advantages in low-energy high-speed
photodetection, although they suffer from serious drawbacks such as an intrinsically high …

For many materials, a precise knowledge of their dispersion spectra is insufficient to predict
their ordered phases and physical responses. Instead, these materials are classified by the …

Chirality—the geometric property of objects that do not coincide with their mirror image—is
found in nature, for example, in molecules, crystals, galaxies and life forms. In quantum field …

Topological materials discovery has evolved at a rapid pace over the past 15 years following
the identification of the first nonmagnetic topological insulators (TIs), topological crystalline …
