Nature of excitations of the 5/2 fractional quantum Hall effect
Résumé
We show, with the help of exact diagonalization studies on systems with up to sixteen electrons in the presence of up to two delta function impurities, that the Pfaffia n model is not accurate for the actual quasiholes and quasiparticles of the 5/2 fractional quantum Hall effect. We discuss implications for non-Abelian statistics.
