The bulk theory is associated with the $c=-2$ conformal field theory. The topological properties of the state, such as the quasiparticle braiding statistics and ground state degeneracy on a torus, may be deduced from this conformal field theory. The 10-fold degeneracy on a torus is explained by the existence of a logarithmic operator in the $c=-2$ theory; this operator corresponds to a novel bulk excitation in the quantum Hall state. We argue that the edge theory is the $c=1$ chiral Dirac fermion, which is related in a simple way to the $c=-2$ theory of the bulk. This theory is reformulated as a truncated version of a doublet of Dirac fermions in which the $SU(2)$ symmetry -- which corresponds to the spin-rotational symmetry of the quantum Hall system -- is manifest and non-local. We make predictions for the current-voltage characteristics for transport through point contacts.", "revisions": [ { "version": "v2", "updated": "1997-03-05T00:08:56.000Z" } ], "analyses": { "subjects": [ "73.40.Hm", "73.20.Dx", "11.25.Hf" ], "keywords": [ "conformal field theory", "haldane-rezayi quantum hall state", "quantum hall system", "ground state degeneracy", "chiral dirac fermion" ], "tags": [ "journal article" ], "publication": { "publisher": "Elsevier", "journal": "Nucl.
