Possible Experimental Realization of a Basic Z2 Topological Semimetal
Erik Haubold, Alexander Fedorov, Igor P. Rusinov +15
We report experimental and theoretical evidence that GaGeTe is a basic topological semimetal with three types of charge carriers: bulk-originated electrons and holes as well…
Chiral Topological Semimetal with Multifold Band Crossings and Long Fermi arcs
Niels B. M. Schröter, Ding Pei, Maia G. Vergniory +14
Topological semimetals in crystals with a chiral structure (which possess a handedness due to a lack of mirror and inversion symmetries) are expected to display numerous exotic phy…
Energy scale of nematic ordering in the parent iron-based superconductor:BaFe2As2
Alexander Fedorov, Alexander Yaresko, Erik Haubold +6
Nematicity plays an important role in the physics of iron-based superconductors (IBS). Its microscopic origin and in particular its importance for the mechanism of high-temperature…
Observation of band crossings protected by nonsymmorphic symmetry in the layered ternary telluride Ta3SiTe6
Takafumi Sato, Zhiwei Wang, Kosuke Nakayama +8
We have performed angle-resolved photoemission spectroscopy of layered ternary telluride Ta3SiTe6 which is predicted to host nodal lines associated with nonsymmorphic crystal symme…
Observation of Chiral Fermions with a Large Topological Charge and and Associated Fermi-Arc Surface States in CoSi
Daichi Takane, Zhiwei Wang, Seigo Souma +12
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-…
Massive Dirac fermions in layered BaZnBi
S. Thirupathaiah, D. Efremov, Y. Kushnirenko +7
Using angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT) we study the electronic structure of layered BaZnBi. Our experimental results show n…
