非阿贝尔两分量分数量子Hall态

Non-Abelian Two-component Fractional Quantum Hall States

Maissam Barkeshli, Xiao-Gang Wen

摘要:

分数量子霍尔(Fractional Quantum Hall,简称FHH)态可以根据它们的零点模式进行分类,它描述了当各种电子簇聚集在一起时基态波函数中的零点的顺序。零点模式方法可以推广到多层/自旋非极化的量子态的系统分类,这导致了一类非阿贝尔多组分量子态的构建。本文讨论了我们发现的几种最简单的非阿贝尔双组分态,以及它们在双层体系中实验实现的可能性,如$ν= 2/3$、4/5、4/7、4/9、1/4等。

英文摘要:

A large class of fractional quantum Hall (FQH) states can be classified according to their pattern of zeros, which describes the order of zeros in ground state wave functions as various clusters of electrons are brought together. The pattern-of-zeros approach can be generalized to systematically classify multilayer/spin-unpolarized FQH states, which has led to the construction of a class of non-Abelian multicomponent FQH states. Here we discuss some of the simplest non-Abelian two-component states that we find and the possibility of their experimental realization in bilayer systems at $ν= 2/3$, 4/5, 4/7, 4/9, 1/4, etc.
