Magnetoresistance originates from decoherence throughout the Fermi sea, with conductivity parameterized by two complex decoherence times that scales linearly with impurity density, unlike the inverse scaling in the Drude model.
Nodal-line semimetals show two quantum oscillation frequencies from their torus Fermi surface and nonsaturating but modest magnetoresistivity in low-energy models.
