Marquardt" ], "categories": [ "cond-mat.mes-hall" ], "abstract": "Topological states of matter are particularly robust, since they exploit global features insensitive to local perturbations. In this work, we describe how to create a Chern insulator of phonons in the solid state. The proposed implementation is based on a simple setting, a dielectric slab with a suitable pattern of holes. Its topological properties can be wholly tuned in-situ by adjusting the amplitude and frequency of a driving laser that controls the optomechanical interaction between light and sound. The resulting chiral, topologically protected phonon transport along the edges can be probed completely optically. Moreover, we identify a regime of strong mixing between photon and phonon excitations, which gives rise to a large set of different topological phases. This would be an example of a Chern insulator produced from the interaction between two physically very different particle species, photons and phonons.", "revisions": [ { "version": "v1", "updated": "2014-09-18T17:00:27.000Z" } ], "analyses": { "subjects": [ "42.50.Wk", "42.65.Sf" ], "keywords": [ "topological phases", "chern insulator", "local perturbations", "solid state", "particle species" ], "publication": { "doi": "10.1103/PhysRevX.5.031011", "journal": "Physical Review X", "year": 2015, "month": "Jul", "volume": 5, "number": 3, "pages": "031011" }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015PhRvX...5c1011P" } } }
