An inhomogeneous Dirac cone system gives rise to in-plane chiral Landau levels

Chiral zeroth Landau levels are topologically protected bulk states that propagate in a single direction. In the field of quantum field theory and condensed matter physics, these levels are crucial for breaking chiral symmetry and triggering the chiral anomaly, which involves the non-conservation of chiral currents in both particle physics and condensed matter systems.
