Topological interface modes in local resonant acoustic systems
Degang Zhao, Meng Xiao, C. W. Ling +2
Topological phononic crystals (PCs) are periodic artificial structures which can support nontrivial acoustic topological bands, and their topological properties are linked to the e…
Anomalous Light Scattering by Topological -symmetric Particle Arrays
C. W. Ling, Ka Hei Choi, T. C. Mok +2
Robust topological edge modes may evolve into complex-frequency modes when a physical system becomes non-Hermitian. We show that, while having negligible forward optical extinction…
Simultaneous Multi-frequency Topological Edge Modes between One-dimensional Photonic Crystals
Ka Hei Choi, C. W. Ling, K. F. Lee +2
We show theoretically that, in the limit of weak dispersion, one-dimensional (1D) binary centrosymmetric photonic crystals can support topological edge modes in all photonic band g…
Formation of Non-reciprocal Bands in Magnetized Diatomic Plasmonic Chains
C. W. Ling, Jin Wang, Kin Hung Fung
We show that non-reciprocal bands can be formed in a magnetized periodic chain of spherical plasmonic particles with two particles per unit cell. Simplified form of symmetry operat…
Non-reciprocal mu-near-zero mode in PT-symmetric magnetic domains
Jin Wang, Hui Yuan Dong, Chi Wai Ling +2
We find that a new type of non-reciprocal modes exist at an interface between two \emph{parity-time} () symmetric magnetic domains (MDs) near the frequency of zero ef…
Topological Edge Plasmon Modes between Diatomic Chains of Nanoparticles
C. W. Ling, Meng Xiao, C. T. Chan +2
We study the topological edge plasmon modes between two "diatomic" chains of identical plasmonic nanoparticles. Zak phase for longitudinal plasmon modes in each chain is calculated…
