Discovery of a Three-dimensional Topological Dirac Semimetal, Na3Bi
Z. K. Liu, B. Zhou, Z. J. Wang +9
Three-dimensional (3D) topological Dirac semimetals (TDSs) represent a novel state of quantum matter that can be viewed as '3D graphene'. In contrast to two-dimensional (2D) Dirac…
Electronic Structure of the Metallic Antiferromagnet PdCrO Measured by Angle-Resolved Photoemission Spectroscopy
Jonathan A. Sobota, Kyoo Kim, Hiroshi Takatsu +8
PdCrO is material which has attracted interest due to the coexistence of metallic conductivity associated with itinerant Pd 4d electrons and antiferromagnetic order arising fro…
Oscillatory surface dichroism of an insulating topological insulator Bi2Te2Se
M. Neupane, S. Basak, N. Alidoust +16
Using circular dichroism-angle resolved photoemission spectroscopy (CD-ARPES), we report a study of the effect of angular momentum transfer between polarized photons and topologica…
Broken relationship between superconducting pairing interaction and electronic dispersion kinks in LSCO
S. R. Park, Y. Cao, Q. Wang +5
Electronic band dispersions in copper oxide superconductors have kinks around 70 meV that are typically attributed to coupling of electrons to a bosonic mode. We performed angle re…
