A unified framework classifies non-Hermitian skin effects into electric (imaginary scalar potential) and magnetic (imaginary vector potential) types, identifies boundary-insensitive modes, and reveals a delocalization phase transition.
Their eigenstates localize strictly at the first site, interpreted as remnants of the N th-order exceptional point under open boundaries, unaffected by the long-range coupling

A Unified Framework for the Non-Hermitian Localization: Boundary-Insensitive Modes and Electric-Magnetic Analogy
A unified framework classifies non-Hermitian skin effects into electric (imaginary scalar potential) and magnetic (imaginary vector potential) types, identifies boundary-insensitive modes, and reveals a delocalization phase transition.
