What is generalized brilioun zone? 


Best insight from top research papers

The Generalized Brillouin Zone (GBZ) is a concept introduced in the study of non-Hermitian systems to describe non-trivial topological structures in boundary conditions between open and periodic boundaries. It plays a crucial role in characterizing phenomena like the non-Hermitian skin effect and topological phase transitions in such systems. By extending the applications of GBZ theory, researchers have been able to provide a more comprehensive understanding of non-Hermitian topological matter. The GBZ theory helps in explaining the behavior of systems with on-site disorders, long-range hopping, and the impact of magnetic suppression on the non-Hermitian skin effect, contributing significantly to the exploration of topological phases in non-Hermitian systems.
