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 …

Three-dimensional (3D) topological semimetals represent a new class of topological
matters. The study of this family of materials has been at the frontiers of condensed matter …

In recent years, the notion of'Quantum Materials' has emerged as a powerful unifying
concept across diverse fields of science and engineering, from condensed-matter and …

Exotic massless fermionic excitations with nonzero Berry flux, other than the Dirac and Weyl
fermions, could exist in condensed matter systems under the protection of crystalline …

The intense theoretical and experimental interest in topological insulators and semimetals
has established band structure topology as a fundamental material property. Consequently …

Weyl semimetals are conductors whose low-energy bulk excitations are Weyl fermions,
whereas their surfaces possess metallic Fermi arc surface states. These Fermi arc surface …

We have given a summary on our theoretical predictions of three kinds of topological
semimetals (TSMs), namely, Dirac semimetal (DSM), Weyl semimetal (WSM) and node-line …

We review recent theoretical progress in the understanding and prediction of novel
topological semimetals. Topological semimetals define a class of gapless electronic phases …

The peculiar band structure of semimetals exhibiting Dirac and Weyl crossings can lead to
spectacular electronic properties such as large mobilities accompanied by extremely high …

In quantum field theory, Weyl fermions are relativistic particles that travel at the speed of light
and strictly obey the celebrated Lorentz symmetry. Their low-energy condensed matter …
