The Hatano–Nelson model is a cornerstone of non‐Hermitian physics, describing asymmetric hopping dynamics on a 1D lattice, which gives rise to fascinating phenomena such as directional transport, non‐Hermitian topology, and the non‐Hermitian skin effect. It has been widely studied in both classical...
