As a result we have found an equivalent representation of the eigenspectrum in terms of the spin-1/2 antiferromagnetic XXZ chain at $\\Delta = - 5/3$. The values of thermodynamic quantities such as the ground state energy and mass gap follow from the known XXZ results.", "revisions": [ { "version": "v1", "updated": "1999-07-30T06:21:45.000Z" } ], "analyses": { "keywords": [ "ground state energy", "generalised quantum spin ladder", "mass gap", "antiferromagnetic xxz chain", "ladder hamiltonian" ], "tags": [ "journal article" ], "note": { "typesetting": "LaTeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable" } } }
