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 cross section, a conjugate pair of such complex topological edge mode

We demonstrate theoretically the electric tunability due to coalescence of exceptional points in PT-symmetric waveguides bounded by imperfect conductive layers. Owing to the competition effect of multimode interaction, multiple exceptional points and

By considering parity-time (PT) symmetric plasmonic chains, an array of plasmonic nanoparticles coated alternatively by gain-loss balanced dielectrics, we demonstrate that it supports topological edge states with quantized Zak phase when there is no

By considering an array of plasmonic nanoparticles coated alternatively by gainloss balanced dielectrics, we demonstrate that a PT-symmetric chain can support topological edge modes with quantized Zak phases if the bulk modes for all real Bloch's wav

In Hong Kong, bacterial pathogens, the majority of them Salmonellae, cause approximately one-third of paediatric admissions for diarrhoea. This study retrospectively reviewed inpatient gastro-enteritis management, with particular focus on antibiotic

In the past, polymer materials have been used in electronic devices; however, the major drawback with polymers is their low thermal conductivity, i.e., 0.1–0.5 W/(m・K). Hence, researchers came up with the idea of incorporating conductive fillers
