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 ...
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 ...
