In lattice regularization, the problem manifests itself as mirror fermions (or doublers) as suggested by the Nielsen-Ninomiya&#8217;s theorem. However, this problem is not a technical but fundamental, since it is also closely related to the existence of anomalies. On the other hand, we find many examples of chiral fermions in nature. Some of them are realized as the edge-modes which appears at the surface of the of &hellip;"}
