A minimal model for the Weyl nodes and Fermi arcs of PtBi${}_2$

Tobias Cristófoli, Manuel Alonso Lemos, Jorge I. Facio +1

Weyl semimetals host topologically protected Fermi arcs on their surfaces, originating from the Chern number of the bulk Weyl nodes. In trigonal PtBi${}_2$, superconducting signature…
