Pursuing topological phases in natural and artificial materials is one of the central topics in
modern physical science and engineering. In classical magnetic systems, spin waves (or …

Measuring topological invariants is an essential task in characterizing topological phases of
matter. They are usually obtained from the number of edge states due to the bulk-edge …

The discovery of topological materials has motivated recent developments to export
topological concepts into photonics to make light behave in exotic ways. Here, we predict …

Symmetries play a major role in identifying topological phases of matter and in establishing
a direct connection between protected edge states and topological bulk invariants via the …

Plasmonic lattices of metal nanoparticles have emerged as an effective platform for strong
light–matter coupling, lasing, and Bose–Einstein condensation. However, the full potential of …

Quantum emitters interacting with photonic band-gap materials lead to the appearance of
qubit-photon bound states that mediate decoherence-free, tunable emitter-emitter …

Abstract The Su–Schrieffer–Heeger (SSH) model perhaps is the easiest and the most basic
model for topological excitations. Many variations and extensions of the SSH model have …

We investigate the symmetry resolution of entanglement in the presence of long-range
couplings. To this end, we study the symmetry-resolved entanglement entropy in the ground …

Longer-range interactions, or couplings beyond the second nearest neighbors, have long
been overlooked in topological models for either topological insulators or semimetals. For …

Symmetries play a paramount role in many aspects of topological physics. A particularly
illuminating example is the Su-Schrieffer-Heeger (SSH) chain, whose reflection and chiral …
