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 …

W annier90 is an open-source computer program for calculating maximally-localised
Wannier functions (MLWFs) from a set of Bloch states. It is interfaced to many widely used …

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 …

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

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 …

Weyl semimetals are crystals in which electron bands cross at isolated points in momentum
space. Associated with each crossing point (or Weyl node) is a topological invariant known …

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 …

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 …

The geometry of quantum states is well established as a basis for understanding the
response of electronic systems to static electromagnetic fields, as exemplified by the theory …
