Symmetry protected topological phases
Webof matter, the so-called symmetry-protected topological (SPT) phases6. In the noninteracting limit, topological insulators and superconductors provide well-understood examples of this paradigm7, while current research aims at understanding strong-correlation effects, such as the competition of SPT and SSB phases, due to interactions8. WebBand topology of materials describes the extent Bloch wavefunctions are twisted in …

Free shipping for many products! WebSpecifically, multiple coherent sources are imported at symmetrical positions in higher-order topological photonic crystals. By engineering phase differences among the sources, a controllable spatial-resolved excitation of topological corner states is realized and a coding technique via controllable excitation of topological corner states is raised conceptually.

In solid state physics, by a phase of matter which is. symmetry … WebIndeed, we show that topological phenomena can be stable over a large part of parameter space even when the bulk is strictly speaking in a trivial phase of matter. In particular, we focus on symmetry-protected topological phases which can be trivialized by extending the symmetry group.
WebFinally, we explored a new type of photonic topological insulator in the developed nanophotonic silicon platform, based on symmetry breaking and spin-orbit coupling in photonic crystals. We directly observed the associated topologically protected edge states and characterized their dispersion, spin, and backscattering-free routing for the first time …
