This approach is employed to obtain a simple pictorial proof of the Zak phase bulk-edge correspondence for any one dimensional system. We apply the transfer matrix method to study some generalisations of the Su-Schrieffer-Heeger (SSH) model, such as the tetramer SSH4 model and a dimerised one-dimensional photonic crystal.", "revisions": [ { "version": "v1", "updated": "2024-06-03T05:28:02.000Z" } ], "analyses": { "keywords": [ "transfer matrix approach", "topological edge states", "zak phase bulk-edge correspondence", "simple pictorial proof", "transfer matrix method" ], "note": { "typesetting": "TeX", "pages": 9, "language": "en", "license": "arXiv", "status": "editable" } } }
