Higher-order exceptional points(EPs), which appear as multifold degeneracies in the spectra of non-Hermitian systems, are garnering extensive attention in various multidisciplinary fields. However, constructing higher...

Photonic topological insulators protected by the lattice spatial symmetry(e.g., inversion and rotation symmetry)mainly support single type edge state, interpreted by either valley or pseudo-spin. Here, we demonstrate ...

We report on the experimental demonstration of two-photon quantum walks at the edge of a photonic Su–Schrieffer–Heeger lattice and compare them to those observed when launching photons at the edge of a homogeneous l...

Activating transitions between internal states of physical systems has emerged as an appealing approach to create lattices and complex networks.In such a scheme,the internal states or modes of a physical system are re...

In this work, we first discuss systematically three general approaches to construct a non-Hermitian flat band,defined by its dispersionless real part. These approaches resort to, respectively, spontaneous restoration ...

Fano resonances between plasmons and diffracted light offer tunable energies and locales,but attribution of Fano resonance features to geometry and physicochemistry of metal nanostructures and adjacent dielectrics has...
