Fermiology and spin polarization of topological surface states in PtBi${}_2$

Anders Christian Mathisen, Xin Liang Tan, Stefanie Suzanne Brinkman +12

Layered PtBi${}_2$ is a candidate for topological superconductivity arising in Fermi-arc surface states. Using spin- and angle-resolved photoemission spectroscopy, we demonstrate tha…
