Author(s): Tian Tian, Shizhen Wang, Yingnan Yan, Tianhan Zhong, Xiaojun Jia, and Heng Shen Non-Hermitian physics has attracted significant interest due to its exotic phenomena. However, non-Hermitian effects at topological interfaces and their potential applications remain largely unexplored. Here, based on an interface skin-effect model, we theoretically propose a non-Hermitian topologic… [Phys. Rev. Lett. 137, 120601] Published Tue Sep 15, 2026
