Experimental observation of anomalous topological edge modes in a slowly driven photonic lattice
Sign Up to like & getrecommendations! Published in 2017 at "Nature Communications"
DOI: 10.1038/ncomms13918
Abstract: Topological quantum matter can be realized by subjecting engineered systems to time-periodic modulations. In analogy with static systems, periodically driven quantum matter can be topologically classified by topological invariants, whose non-zero value guarantees the presence… read more here.
