Fermi surface topology and non-trivial Berry phase in the flat-band semimetal Pd${}_3$Pb

Mojammel A. Khan, Po-Hao Chang, Nirmal Ghimire +5

A study of the Fermi surface of the putative topological semimetal Pd${}_3$Pb has been carried out using Shubnikov-de Haas (SdH) oscillations measured in fields of up to 60 T. Pd${}_3$…
