Spectral Asymmetry Induces a Re‐Entrant Quantum Hall Effect in a Topological Insulator
Abstract The band inversion of topological materials in three spatial dimensions is intimately connected to the parity anomaly of 2D massless Dirac fermions, known from quantum field theory. At finite magnetic fields, the parity anomaly reveals itself as a non‐zero spectral asymmetry, i.e., an imbal...
