阿贝尔和非阿贝尔分数量子Hall态的剖析

The Anatomy of Abelian and Non-Abelian Fractional Quantum Hall States

B. Andrei Bernevig, N. Regnault

摘要:

我们推导出一组新的对称性和阿贝尔和非阿贝尔分数量子霍尔(HHH)在自由(玻色子或费米子)多体状态的展开系数之间的关系。我们的规则允许建立一个近似的模型状态,其重叠随着系统大小的增加而增加(有时可能达到统一!)同时使用原始希尔伯特空间的一小部分。我们证明了这些对称性推导出一个以前未知的递归公式的所有系数的斯莱特展开的劳克林,阅读Rezayi和许多其他国家(所有杰克乘范德蒙决定因素),这完全消除了当前需要对角化程序。

英文摘要:

We deduce a new set of symmetries and relations between the coefficients of the expansion of Abelian and Non-Abelian Fractional Quantum Hall (FQH) states in free (bosonic or fermionic) many-body states. Our rules allow to build an approximation of a FQH model state with an overlap increasing with growing system size (that may sometimes reach unity!) while using a fraction of the original Hilbert space. We prove these symmetries by deriving a previously unknown recursion formula for all the coefficients of the Slater expansion of the Laughlin, Read Rezayi and many other states (all Jacks multiplied by Vandermonde determinants), which completely removes the current need for diagonalization procedures.
