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 …

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 report on a study of the optical properties of CsV 3 Sb 5 for a large number of
temperatures above and below the charge-density-wave (CDW) transition. Above the CDW …

Based on first-principle calculations, we show that a family of nonmagnetic materials
including TaAs, TaP, NbAs, and NbP are Weyl semimetals (WSM) without inversion centers …

We theoretically study three-dimensional topological semimetals (TSMs) with nodal lines
protected by crystalline symmetries. Compared to TSMs with point nodes, eg, Weyl …

The massless solutions to the Dirac equation are described by the so-called Weyl
Hamiltonian. The Weyl equation requires a particle to have linear dispersion in all three …

Recently, the effects of spin-orbit coupling (SOC) in correlated materials have become one
of the most actively studied subjects in condensed matter physics, as correlations and SOC …

Although Weyl fermions have proven elusive in high-energy physics, their existence as
emergent quasiparticles has been predicted in certain crystalline solids in which either …

Abstract A three-dimensional (3D) Dirac semimetal (SM) is the 3D analogue of graphene
having linear energy dispersion around Fermi points. Owing to the nontrivial topology of …

We consider the classical magnetoresistance of a Weyl metal in which the electron Fermi
surface possesses nonzero fluxes of the Berry curvature. Such a system may exhibit large …
