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…
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…
