Observation of Chiral Fermions with a Large Topological Charge and Associated Fermi-Arc Surface States in CoSi
Observation of Chiral Fermions with a Large Topological Charge and Associated Fermi-Arc Surface States in CoSi
Topological semimetals materialize a new state of quantum matter where massless fermions protected by a specific crystal symmetry host exotic quantum phenomena. Distinct from well-known Dirac and Weyl fermions, structurally-chiral topological semimetals are predicted to host new types of massless fermions characterized by a large topological charge, whereas such exotic …
