Our setup involves a deep two dimensional optical lattice with a time dependent superlattice that modulates the hopping between neighboring sites. The finite waist of the superlattice beam yields regions with different topological numbers. One can observe chiral edge states by imaging the real-space density of a bosonic packet launched from the boundary between two topologically distinct regions.", "revisions": [ { "version": "v2", "updated": "2014-06-30T14:47:30.000Z" } ], "analyses": { "subjects": [ "67.85.Hj", "03.65.Vf", "37.10.Jk" ], "keywords": [ "ultracold atoms", "superlattice beam yields regions", "topologically protected floquet edge states", "chiral edge states", "optical lattice" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Physical Review A", "doi": "10.1103/PhysRevA.89.063628", "year": 2014, "month": "Jun", "volume": 89, "number": 6, "pages": "063628" }, "note": { "typesetting": "RevTeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2014PhRvA..89f3628R" } } }
