Prediction of triple point fermions in simple half-Heusler topological insulators
We predict the existence of triple point fermions in the band structure of
several half-Heusler topological insulators by calculations and the
Kane model. We find that many half-Heusler compounds exhibit multiple triple
points along four independent axes, through which the doubly degenerate
conduction bands and the nondegenerate valence band cross each other linearly
nearby the Fermi energy. When projected from the bulk to the (111) surface,
most of these triple points are located far away from the surface
point, as distinct from previously reported triple point fermion
candidates. These isolated triple points give rise to Fermi arcs on the
surface, that can be readily detected by photoemission spectroscopy or scanning
tunneling spectroscopy.Comment: 6 pages, 3 figures. The supplementary information is attached in the
