It is shown, with the help of exact diagonalization studies on systems with up to 16 electrons, in the presence of up to two delta function impurities, that the Pfaffian model is not accurate for the actual quasiholes and quasiparticles of the 5/2 fractional quantum Hall effect. Implications for non-Abelian statistics are discussed.
借助对含有多达16个电子且存在多达两个δ函数杂质的系统进行的精确对角化研究表明,对于5/2分数量子霍尔效应的实际准空穴和准粒子,Pfaffian模型并不准确。文中讨论了对非阿贝尔统计的影响。
