Surface and bulk superconductivity at ambient pressure in the Weyl semimetal TaP
M. R. van Delft, S. Pezzini, M. König +3
The motivation to search for signatures of superconductivity in Weyl semi-metals and other topological phases lies in their potential for hosting exotic phenomena such as nonzero-m…
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…
High-order fractal states in graphene superlattices
R. Krishna Kumar, A. Mishchenko, X. Chen +7
Graphene superlattices were shown to exhibit high-temperature quantum oscillations due to periodic emergence of delocalized Bloch states in high magnetic fields such that unit frac…
