While we use negativity to calculate entanglement, more general non-classical correlations are quantified using a new measure based on a necessary and sufficient condition for zero-discord state. We demonstrate that the energy level crossings in the ground state of the system are signalled by both the behavior of thermal quantum correlations and entanglement.", "revisions": [ { "version": "v1", "updated": "2012-10-01T14:22:45.000Z" } ], "analyses": { "keywords": [ "bose-hubbard model", "thermal quantum correlations", "entanglement", "energy level crossings", "general non-classical correlations" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
