Tunable Chern superconductivity of PtBi${}_2$ in slab geometry

Luca Ketmaier, Jeroen van den Brink, Ion Cosma Fulga

Recent experiments indicate that PtBi${}_2$ is a Weyl semimetal whose surfaces become topological superconductors with i-wave gap symmetry at low temperature. The bulk hosts 12 Weyl…
