Abstract
This work explores a non-Hermitian system displaying a reciprocal variant of the skin effect, which is characterized by an extensive anomalous localization of all Hamiltonian eigenmodes in a one-dimensional geometry. The authors experimentally demonstrate the reciprocal skin effect in a passive RLC circuit and suggest alternative implementations in optical, acoustic, mechanical, and related platforms.
