Quantum oscillations reveal sixfold fermions in cubic ${\hat{I}}^2$-PtBi${}_2$

E. F. Bavaro, J. Castro, V. Vildosola +2

We report a study of de Haas-van Alphen oscillations in high-quality single crystals of cubic ${\hat{I}}^2$-PtBi${}_2$. In combination with density functional theory calculations, we identify…
