Free-carrier dynamics in AuPb probed by optical conductivity measurements
R. Kemmler, R. Hübner, A. Löhle +5
We measured the optical reflectivity of the Dirac material AuPb in a broad frequency range (30 - 48 000 cm) for temperatures between 9 and 300 K. The optical conductiv…
Topological Semimetals in Square-Net Materials
Sebastian Klemenz, Shiming Lei, Leslie M. Schoop
Many materials crystallize in structure types that feature a square-net of atoms. While these compounds can exhibit many different properties, some members of this family are topol…
On the possibility of magnetic Weyl fermions in non-symmorphic compound PtFeSb
M. G. Vergniory, L. Elcoro, F. Orlandi +5
Weyl fermions are expected to exhibit exotic physical properties such as the chiral anomaly, large negative magnetoresistance or Fermi arcs. Recently a new platform to realize thes…
Electron-hole tunneling revealed by quantum oscillations in the nodal-line semimetal HfSiS
M. R. van Delft, S. Pezzini, T. Khouri +6
We report a study of quantum oscillations in the high-field magneto-resistance of the nodal-line semimetal HfSiS. In the presence of a magnetic field up to 31 T parallel to the c-a…
Topological band crossings in hexagonal materials
Jonathan Zhang, Y. -H. Chan, Ching-Kai Chiu +3
Topological semimetals exhibit band crossings near the Fermi energy, which are protected by the nontrivial topological character of the wave functions. In many cases, these topolog…
Chemical Principles of Topological Semimetals
Leslie Schoop, Florian Pielnhofer, Bettina Lotsch
Initiated by the discovery of topological insulators, topologically non-trivial materials have attracted immense interest in the physics community in the past decade. One of the la…
