Determination of the Fermi surface and field-induced quasiparticle tunneling around the Dirac nodal loop in ZrSiS
Unambiguous and complete determination of the Fermi surface is a primary step in understanding the electronic properties of topical metals and semimetals, but only in a relatively few cases has this goal been realized.In this work, we present a systematic high-field quantum oscillation study up to 35 T on ZrSiS, a textbook example of a nodal-line s
