This work is devoted to the rigorous derivation of the celebrated King-Smith and Vanderbilt formula for orbital polarization in a generalized setting that includes continuous random systems among others.", "revisions": [ { "version": "v1", "updated": "2022-10-18T13:47:05.000Z" } ], "analyses": { "subjects": [ "35Q41", "81Q70", "81R60", "82B44" ], "keywords": [ "disordered systems", "topological polarization", "orbital polarization", "ionic cores", "vanderbilt formula" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable" } } }
