Topological quantum states of matter, characterized by geometrical features of electronic band structures, have been extensively studied. Among them, the topological electronic state with magnetic ...

Weyl semimetals are topological materials whose low-energy excitations obey the Weyl equation. In a Weyl semimetal, the conduction and valence bands touch at discrete points in momentum space called ...

IMAGE1: Lattice model and formation of Weyl exceptional rings. a, Schematic of the 3D lattice in a rhombic prism geometry, with three sublattices in a unit cell. b, Distributions of the Weyl points ...

Topology is a global aspect of materials, leading to fundamental new properties for compounds with large relativistic effects. The incorporation of heavy elements gives rise to non-trivial topological ...

Quasiparticles with linear dispersion in condensed matter 1 systems have sparked considerable excitement since their discovery in graphene 2, topological insulators 3, Dirac semimetals such as Na 3 Bi ...
