Casimir induced instabilities at metallic surfaces and interfaces
Kun Ding, Daigo Oue, C. T. Chan +1
Surface plasmons subject to a surface distortion split asymmetrically in energy resulting in a net lowering of zero-point energy. This is because surface plasmon eigenvalues are th…
Angle-Resolved Thermal Emission Spectroscopy Characterization of Non-Hermitian Meta-Crystals
Fan Zhong, Kun Ding, Ye Zhang +3
We establish the angle-resolved thermal emission spectroscopy (ARTES) as a new platform to characterize the intrinsic eigenmode properties of non-Hermitian systems. This method can…
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…
Dynamically encircling an exceptional point in anti-PT-symmetric systems: asymmetric mode switching for symmetry-broken states
Xu-Lin Zhang, Tianshu Jiang, Hong-Bo Sun +1
Dynamically encircling an exceptional point (EP) in parity-time (PT) symmetric systems shows an interesting chiral dynamics, leading to asymmetric mode switching in which the outpu…
Experimental demonstration of an anisotropic exceptional point
Kun Ding, Guancong Ma, Z. Q. Zhang +1
Exceptional points (EPs) associated with a square-root singularity have been found in many non-Hermitian systems. In most of the studies, the EPs found are isotropic meaning that t…
