Quantum oscillations in the zeroth Landau Level and the serpentine Landau fan
T. Devakul, Yves H. Kwan, S. L. Sondhi +1
We identify an unusual mechanism for quantum oscillations in nodal semimetals, driven by a single pair of Landau levels periodically closing their gap at the Fermi energy as a magn…
Quantum oscillations probe the Fermi surface topology of the nodal-line semimetal CaAgAs
Y. H. Kwan, P. Reiss, Y. Han +6
Nodal semimetals are a unique platform to explore topological signatures of the unusual band structure that can manifest by accumulating a nontrivial phase in quantum oscillations.…
`Unhinging' the surfaces of higher-order topological insulators and superconductors
Apoorv Tiwari, Ming-Hao Li, B. A. Bernevig +2
We show that the chiral Dirac and Majorana hinge modes in three-dimensional higher-order topological insulators (HOTIs) and superconductors (HOTSCs) can be gapped while preserving…
Topology- and symmetry-protected domain wall conduction in quantum Hall nematics
Kartiek Agarwal, Mallika T. Randeria, A. Yazdani +2
We consider domain walls in nematic quantum Hall ferromagnets predicted to form in multivalley semiconductors, recently probed by scanning tunnelling microscopy experiments on Bi(1…
