They are directly related to the field derivatives of the determinant of a matrix which describes the topology of the graph. In certain limits, they are obtained by simple counting of the nodes and their connectivity. We relate the average current of a disordered graph with interactions and the non-interacting current of the same graph with clean 1D wires. A similar relation exists for orbital magnetism in general.", "revisions": [ { "version": "v1", "updated": "1999-04-08T16:04:25.000Z" } ], "analyses": { "keywords": [ "persistent currents", "clean 1d wires", "field derivatives", "orbital magnetism", "transport properties" ], "tags": [ "journal article" ], "publication": { "publisher": "APS", "journal": "Phys.
