Exceptional topology of non-Hermitian systems

Emil J. Bergholtz et al.

Summary: This review discusses the current understanding of the role of topology in non-Hermitian systems and its physical consequences in dissipative settings, focusing on the concept of exceptional degeneracies and its distinct phenomena, as well as the new notions of gapped phases in single-band systems. The unique sensitivity of non-Hermitian matrices to boundary conditions is highlighted, leading to anomalous relationships between bulk and boundary physics. Additionally, applications of non-Hermitian topology in classical and quantum systems are reviewed, showing its relevance beyond the field of topological phases.

Dynamical robustness of topological end states in nonreciprocal Su-Schrieffer-Heeger models with open boundary conditions

Li-Jun Lang et al.

Summary: This study explores the dynamics of initial end states in nonreciprocal Su-Schrieffer-Heeger models under open boundary conditions, finding that they are more robust compared to their Hermitian counterparts due to the non-Hermitian skin effect. By proposing a classical electric circuit, the researchers establish a mapping to the quantum model, offering an easy way to study nonreciprocal quantum dynamics and potentially inspiring more dynamical studies of non-Hermitian models on other platforms.
