Exceptional Cones in 4D Parameter Space
Qiang Wang, Kun Ding, Hui Liu +2
The notion of synthetic dimensions has expanded the realm of topological physics to four dimensional (4D) space lately. In this work, non-Hermiticity is used as a synthetic paramet…
Realization of Photonic Charge-2 Dirac Point by Engineering Super-modes in Topological Superlattices
Mengying Hu, Kun Ding, Tong Qiao +4
Quite recently a novel variety of unconventional fourfold linear band degeneracy points has been discovered in certain condensed-matter systems. Contrary to the standard 3-D Dirac…
Plasmon Localization Assisted by Conformal Symmetry
Lizhen Lu, Emanuele Galiffi, Kun Ding +3
Plasmonic systems have attracted remarkable interest due to their application to the subwavelength confinement of light and the associated enhancement of light-matter interactions.…
Realization of complex conjugate media using non-PT-symmetric photonic crystals
Xiaohan Cui, Kun Ding, Jianwen Dong +1
While parity-time (PT)-symmetric systems can exhibit real spectra in the exact PT-symmetry regime, the PT-symmetry is actually not a necessary condition for the real spectra. Here…
Machine prediction of topological transitions in photonic crystals
Bei Wu, Kun Ding, C. T. Chan +1
We train artificial neural networks to distinguish the geometric phases of a set of bands in 1D photonic crystals. We find that the trained network yields remarkably accurate predi…
Exceptional points and their coalescence of PT-symmetric interface states in photonic crystals
Xiaohan Cui, Kun Ding, Jian-Wen Dong +1
The existence of surface electromagnetic waves in the dielectric-metal interface is due to the sign change of real parts of permittivity across the interface. In this work, we demo…
