From Nodal Chain Semimetal to Weyl Semimetal in HfC [PDF]
Physical Review Letters, 2017 Based on first-principles calculations and effective model analysis, we propose that the WC-type HfC, in the absence of spin-orbit coupling (SOC), can host a three-dimensional nodal chain semimetal state. Distinguished from the previous material IrF4 [T.

Hydrodynamics of Weyl Semimetals
2022Weyl semimetals are three dimensional topological states of matter whose band structures are characterized by the presence of points of degeneracy between bands near the Fermi energy. These points can appear in three-dimensional materials that break at least one of inversion or time reversal symmetry.

Quantum Simulation Many compounds have now been identified as Weyl semimetals, materials with an unusual electronic band structure characterized by the so-called Weyl points. Weyl points always appear in pairs, but the solid-state materials studied so far have at least four. Wang et al.

Nous étudions les propriétés d'un semi-métal de Weyl (WSM) -- un matériel trois-dimensionnel topologique -- quand ce-dernier est jumelé à un métal non-topologique. Lorsque cela prend place, les états quantiques à l'interface entre les deux matériaux dévoilent deux phénomènes principaux.

Topological Matter Weyl semimetals (WSMs)—materials that host exotic quasiparticles called Weyl fermions—must break either spatial inversion or time-reversal symmetry. A number of WSMs that break inversion symmetry have been identified, but showing unambiguously that a material is a time-reversal-breaking WSM is tricky.

Topological valley pumping in Weyl semimetals
Journal of Physics: Condensed Matter, 2019Abstract We investigate the topological pumping effect in Weyl semimetals, subject to the modulation of two ac electric fields along y and z directions, respectively.
