Claims

C1strongest claim

The analysis of quantum oscillations and Hall conductivity shows that the Fermi velocity is nearly independent of the cross-sectional area of the Fermi surface, or equivalently the carrier density, supporting a k-linear dispersion of the Dirac node.

C2weakest assumption

That the quantum oscillations and Hall conductivity arise predominantly from the Dirac nodes rather than from other bands, impurities, or surface states that could produce similar signals.

C3one line summary

In CaIrO3 the Fermi velocity remains nearly constant across carrier densities, confirming k-linear Dirac dispersion, while magnetoresistance field scaling shifts from linear to super-quadratic at low densities due to enhanced Coulomb interactions in the quantum limit.
