The reciprocal skin effect and its realization in a topolectric circuit

The non-Hermitian skin effect constitutes a new paradigm in the research and design of synthetic metamaterials. It fundamentally relies on the combined breaking of Hermiticity and reciprocity. In this talk, we present the novel approach of obtaining extensive eigenmode localization in the presence of reciprocity. In contrast to non-reciprocal implementations of the Skin effect which require an external energy supply, our approach can be implemented by exclusively passive components. We demonstrate this in a passive RLC circuit network. The reciprocal Skin effect suggests itself for realizations in a plethora of metamaterial platforms with limited availability of active components.
