该研究通过宏观运动的电子液体在祖巴列夫统计算符方法中,证明了相互作用对分数量子霍尔电导的非重整化特性。

摘要:

我们研究了洛佩兹和弗拉季金[1]多年来提出的分数量子霍尔效应(QHE)理论,用于描述主要的贾因系列。统计规范场附着在电子上的磁通量在与电子液体一起运动的参考系中保持静止。在实验室参考系中,统计规范场的电场形成并屏蔽外部电场。分数QHE电导出现于该屏蔽在平均场理论水平上。我们考虑了该模型的相对论扩展,并提出了一种基于宏观运动的电子液体在祖巴列夫统计算符方法中的替代描述。正是这种电子的宏观运动在此模式中导致了分数QHE。在此方法中,我们提出了一个证明,表明在扰动理论的任意阶次中,相互作用修正不能改变上述平均场理论结果中的QHE电导。

英文摘要:

We investigate the theory of the fractional quantum Hall effect (QHE) proposed a long time ago by Lopez and Fradkin \cite{Fradkin1991chern} to describe the principal Jain series. The magnetic fluxes of the statistical gauge field attached to electrons remain at rest in the reference frame moving together with the electron liquid. In the laboratory reference frame the electric field of the statistical gauge field forms and screens the external electric field. The fractional QHE conductivity appears as a consequence of this screening already on the mean field theory level. We consider a relativistic extension of the model, and propose an alternative description of the fractional QHE based on macroscopic motion of the electron liquid within the Zubarev statistical operator approach. It is this macroscopic motion of electrons which in this pattern gives rise to the fractional QHE. Within this approach we propose the proof to all orders of perturbation theory that the interaction corrections cannot change the above mentioned mean field theory result for the QHE conductivity.
