Real-space imaging of a topologically protected edge state with ultracold atoms in an amplitude-chirped optical lattice
To describe a mobile defect in polyacetylene chains, Su, Schrieffer and Heeger formulated a model assuming two degenerate energy configurations that are characterized by two different topological phases. An immediate consequence was the emergence of a soliton-type edge state located at the boundary...
