Observation of topologically enabled complete polarization conversion
Fujia Chen, Zhen Gao, Li Zhang +8
Exploiting topological ideas has been a major theme in modern photonics, which provides unprecedented opportunities to design photonic devices with robustness against defects and f…
Non-Hermitian skin effect and delocalized edge states in photonic crystals with anomalous parity-time symmetry
Qinghui Yan, Hongsheng Chen, Yihao Yang
Non-Hermitian skin effect denotes the exponential localization of a large number of eigen-states in a non-Hermitian lattice under open boundary conditions. Such a non-Hermiticity-i…
Topological chiral edge states in deep-subwavelength valley photonic metamaterials
Rui Xi, Qiaolu Chen, Qinghui Yan +5
Topological valley photonics has emerged as a new frontier in photonics with many promising applications. Previous valley boundary transport relies on kink states at internal bound…
Unconventional Weyl exceptional contours in non-Hermitian photonic continua
Qinghui Yan, Qiaolu Chen, Li Zhang +3
Unconventional Weyl points with topological charges higher than 1 can transform into various complex unconventional Weyl exceptional contours under non-Hermitian perturbations. How…
Acoustic non-Hermitian skin effect from twisted winding topology
Li Zhang, Yihao Yang, Yong Ge +11
The recently discovered non-Hermitian skin effect (NHSE) manifests the breakdown of current classification of topological phases in energy-nonconservative systems, and necessitates…
