New Trends of Non-Hermitian Topology in Open and Correlated Quantum Systems
Non-Hermiticity plays a central role in describing open systems, which in recent years has been investigated in the context of topology revealing a dramatic enrichment of the phenomenology of topological phases. A particular focus has been on the appearance of truly non-Hermitian (NH) degeneracies known as exceptional points (EPs) at which not only the eigenvalues but also the eigenvectors coalesce. In their most elementary form, EPs reveal intriguing phenomena, such as unidirectional transmission, and one-sided visibility. Due to the novelty of the field, research has only recently started to dive into the topic of higher-order EPs, and the importance of EPs beyond classical systems.…
