Disentangling bulk and surface states in the electronic structure of PtBi(0001)
Stefanie Suzanne Brinkman, Xin Liang Tan, Anders Christian Mathisen +13
Recent reports of surface-localized topological superconductivity in trigonal PtBi highlight the importance of understanding its surface electronic structure. We investigate th…

A minimal model for the Weyl nodes and Fermi arcs of PtBi
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, superconducting signature…

Fermiology and spin polarization of topological surface states in PtBi
Anders Christian Mathisen, Xin Liang Tan, Stefanie Suzanne Brinkman +12
Layered PtBi is a candidate for topological superconductivity arising in Fermi-arc surface states. Using spin- and angle-resolved photoemission spectroscopy, we demonstrate tha…
