论文摘要
我们研究$ν= {\ pm} 1/2 $ $ n $ sibrov等人观察到的石墨烯中的分数量子霍尔。 [Nat。物理。 14，930（2018）]。采用Parton构造为这些状态提供山谷的非极化试验波函数。在汉密尔顿的晶格量表谷各向异性术语软化了不同山谷中电子之间的排斥，从而有利于山谷非极化状态。我们提案的有效性通过数值计算来证实。
We study the $ν={\pm}1/2$ fractional quantum Hall states in graphene observed by Zibrov et al. [Nat. Phys. 14, 930 (2018)]. The parton construction is employed to provide a valley unpolarized trial wave function for these states. The lattice scale valley anisotropic terms in the Hamiltonian soften the repulsion between electrons in different valleys to favor the valley unpolarized state. The validity of our proposal is corroborated by numerical calculations.
