Superconductivity and a van Hove singularity confined to the surface of a topological semimetal

Superconductivity and a van Hove singularity confined to the surface of a topological semimetal

Abstract The interplay between topology and superconductivity generated great interest in condensed matter physics. Here, we unveil an unconventional two-dimensional superconducting state in the Dirac nodal line semimetal ZrAs2 which is exclusively confined to the top and bottom surfaces within the...
