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 photoexcitation life cycle from incident photon (and creation of photoexcited electron–
hole pair) to ultimate extraction of electrical current is a complex multiphysics process …

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 …

The past decade has witnessed a surge of interest in exploring emergent particles in
condensed matter systems. Novel particles, emerged as excitations around exotic band …

Reflection and refraction of waves occur at the interface between two different media. These
two fundamental interfacial wave phenomena form the basis of fabricating various wave …

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 …

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

The quantum behaviour of electrons in materials is the foundation of modern electronics and
