我们进行数值研究，以确定在填充因子 v = 5/2 时观察到的分数量子霍尔态是否是摩尔-里德波函数或其粒子空穴共轭，即所谓的反普法夫函数。使用截断希尔伯特空间方法，我们发现，对于现实相互作用，包括朗道级混合，基态保持完全极化，并且反普法夫方程受到强烈青睐。
We perform numerical studies to determine if the fractional quantum Hall state observed at a filling factor of v = 5/2 is the Moore-Read wave function or its particle-hole conjugate, the so-called anti-Pfaffian. Using a truncated Hilbert space approach we find that, for realistic interactions, including Landau-level mixing, the ground state remains fully polarized and the anti-Pfaffian is strongly favored.
