This model exhibits a type of localization known as Stark many-body localization. The dynamics shows a strong dependence on the initial conditions, indicating that the system violates the eigenstate thermalization hypothesis at any finite gradient of the potential. This is contrary to reports of a numerically observed ergodic phase. Therefore, the localization is crucially distinct from disorder-driven many-body localization, in agreement with recent predictions on the basis of localization via Hilbert-space shattering.", "revisions": [ { "version": "v1", "updated": "2020-12-26T11:51:55.000Z" } ], "analyses": { "keywords": [ "stark many-body localization", "hilbert-space shattering", "disorder-driven many-body localization", "interacting quantum spin chain", "eigenstate thermalization hypothesis" ], "note": { "typesetting": "TeX", "pages": 6, "language": "en", "license": "arXiv", "status": "editable" } } }
