Determination of the Fermi surface and field-induced quasiparticle tunneling around the Dirac nodal loop in ZrSiS

In this work, the authors present the determination of the Fermi surface of the Dirac nodal-line semimetal ZrSiS. Using a high-field quantum oscillation study and taking into account the restraints on the Fermi surface topology due to magnetic breakdown, the authors show that enhanced scattering residing on the electron pocket is present.
