Topological transitions in arrays of dipoles coupled to a cavity waveguide
Topological valley-Hall edge states have been realized in a variety of photonic structures across the electromagnetic spectrum because they can be easily engineered by breaking certain lattice symmetries. However, the valley-Chern numbers that characterize the topological phase are usually fixed by...
