Non-Hermitian topology and exceptional-point geometries
Non-Hermitian theory is a theoretical framework used to describe open systems. It offers a
powerful tool in the characterization of both the intrinsic degrees of freedom of a system and …

Non-Hermitian topological sensors
We introduce and study a novel class of sensors whose sensitivity grows exponentially with
the size of the device. Remarkably, this drastic enhancement does not rely on any fine …

Self-healing of non-Hermitian topological skin modes
S Longhi - Physical Review Letters, 2022 - APS
A unique feature of non-Hermitian (NH) systems is the NH skin effect, ie, the edge
localization of an extensive number of bulk-band eigenstates in a lattice with open or semi …
