As a function of the interaction $V$ the phase diagram has a rich structure. There exist gapless phases with dominating density-density correlations (metallic) or pair-pair correlations (superconducting) as well insulating and phase-separated phases. The stiffness constant of the conductivity, the effective transport mass, and the compressibility are also exactly calculated in several regions of the phase diagram.", "revisions": [ { "version": "v1", "updated": "1997-06-23T16:14:05.000Z" } ], "analyses": { "keywords": [ "phase diagram", "exactly solvable model", "superconducting properties", "correlated hopping", "interaction" ], "tags": [ "journal article" ], "note": { "typesetting": "LaTeX", "pages": 11, "language": "en", "license": "arXiv", "status": "editable" } } }
