Abstract

We present a microscopic theory of the neutral collective modes supported by the non-Abelian fractional quantum Hall states at filling factor 5/2. The theory is formulated in terms of the trial states describing the Girvin-MacDonald-Platzman mode and its fermionic counterpart. These modes are superpartners of each other in a concrete sense, which we elucidate.

摘要

我们提出了一种关于填充因子为5/2的非阿贝尔分数量子霍尔态所支持的中性集体模式的微观理论。该理论是根据描述吉尔文 - 麦克唐纳 - 普拉茨曼模式及其费米子对应物的试探态来构建的。从具体意义上讲，这些模式是彼此的超对称伙伴，我们对此进行了阐释。
