The origin for both is the phase coherence of condensate wave-functions. Some relevant issues are also addressed.", "revisions": [ { "version": "v1", "updated": "2001-04-19T09:19:25.000Z" } ], "analyses": { "keywords": [ "off-diagonal long-range order", "irrotational flow", "quantization", "circulation", "connected region" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
