Study reveals non-Hermitian skin effect linked to topology

phys.org

A study led by Dr. Haiping Hu from the Institute of Physics, Chinese Academy of Sciences, published in Science Bulletin, investigates the non-Hermitian skin effect (NHSE) across all dimensions. The research reveals that NHSE, characterized by eigenstate accumulation at boundaries, can be analyzed using non-Bloch band theory. The findings enhance understanding of NHSE's topological origins and its implications for various physical systems, including optical and photonic applications.
