Conformal field theory approach to Abelian and non-Abelian quantum Hall quasielectrons.

摘要: The quasiparticles in quantum Hall liquids carry fractional charge and obey statistics. Of particular recent interest are those with non-Abelian statistics, since their braiding properties could, principle, be used for robust coding of information. There is already a good theoretical understanding quasiholes both Abelian states. Here we develop conformal field theory methods that allow an equally precise description quasielectrons explicitly construct two- four-quasielectron excitations the Moore-Read state.
