Journal ArticleDOI
Biorthogonal Bulk-Boundary Correspondence in Non-Hermitian Systems.
TL;DR: This work provides a comprehensive framework for generalized bulk-boundary correspondence and a quantized biorthogonal polarization that is formulated directly in systems with open boundaries, including exactly solvable non-Hermitian extensions of the Su-Schrieffer-Heeger model and Chern insulators.
Journal ArticleDOI
Exceptional topology of non-Hermitian systems
TL;DR: In this paper, the role of topology in non-Hermitian (NH) systems and its far-reaching physical consequences observable in a range of dissipative settings are reviewed.
Journal ArticleDOI
Corner states of light in photonic waveguides
Ashraf Mohamed El Hassan,Flore K. Kunst,Alexander Moritz,G. Andler,Emil J. Bergholtz,Mohamed Bourennane +5 more
TL;DR: In this article, the experimental realization of novel corner states made out of visible light in three-dimensional photonic structures inscribed in glass samples using femtosecond laser technology is reported.
Journal ArticleDOI
Topological Flat Band Models and Fractional Chern Insulators
Emil J. Bergholtz,Zhao Liu +1 more
TL;DR: In this article, the authors summarize the basics of tight-binding models hosting nearly flat bands with nontrivial topology, C≠0, and summarize the present understanding of interactions and strongly correlated phases within the model.
Journal ArticleDOI

Ashraf Mohamed El Hassan,Flore K. Kunst,Alexander Moritz,G. Andler,Emil J. Bergholtz,Mohamed Bourennane +5 more
TL;DR: In this article, the experimental realisation of novel corner states made out of classical light in three-dimensional photonic structures inscribed in glass samples using femtosecond (fs) laser technology is reported.
