Year: 2025

Type: article

Abstract: Weyl Semimetal n article number 2419559, Cong Li, Tao Xiang, Oscar Tjernberg, and co-workers provide a feasible experimental platform, the surface reconstructed Weyl semimetal, to incorporate non-Hermitian effects into condensed matter physics for the first time. The emergence of boundary non-Hermitian effects offers valuable insights into the abnormal anomalous Hall effect observed in the Weyl semimetal NdAlSi and suggests that the potential to modify the overall transport properties of topological materials through simple adjustments to their surface atomic arrangements.
