Fig. 3: The cross section of Fermi surfaces and corresponding l-paths.

a–c The typical cross section of Fermi surfaces and (d–f) their corresponding l-paths with the magnetic field along z direction. The chemical potentials are set to (a, d) μ = −55 meV, (b, e) μ = −50 meV, and (c, f) μ = 40 meV, respectively.
