The study of classical wave physics has been reinvigorated by incorporating the concept of
the geometric phase, which has its roots in optics, and topological notions that were …

Topological photonics has emerged as a novel approach to engineering the flow of light and
provides unprecedented means for developing diverse photonic elements, including robust …

The geometric-phase concept has far-reaching implications in many branches of
physics,,,,,,,,,,,,,. The geometric phase that specifically characterizes the topological property …

Topological photonics is an emergent field at the cross of photonics and topological physics
which opens our eyes to novel topological phenomena and versatile photonic effects …

Weyl fermions have not been found in nature as elementary particles, but they emerge as
nodal points in the band structure of electronic and classical wave crystals. Novel …

A boundary mode localized on one side of a finite-size lattice can tunnel to the opposite side
which results in unwanted couplings. Conventional wisdom tells that the tunneling …

The nonequilibrium dynamics of two-dimensional Su-Schrieffer-Heeger model, in the
presence of staggered chemical potential, is investigated using the notion of dynamical …

We propose the mechanism of edge state-led mode coupling under topological protection;
ie, localized surface plasmons almost do not have any influence on the edge state, while the …

In this paper, we investigate the band properties of 2D honeycomb plasmonic lattices
consisting of metallic nanoparticles. By means of the coupled dipole method and quasi-static …

Typically, edge states in graphene are known to exist solely along zigzag edges. However,
in this paper, we present a theoretical discovery of edge states along armchair edges in …
