Pedro L. S. Lopes, V. L. Quito, Bo Han, Jeffrey C. Y. Teo

摘要:

通过理论耦合线模型,我们构造了强关联电子\emph{integer}量子霍尔态.作为一个显著的特征,这些态支持电和热霍尔输运违反Wiedemann-Franz定律作为$\left(κ_{xy}/σ_{xy}\right)/\left[\left(π^{2}k_{B}^{2}T\right)/3e^{2}\right]<1$ .我们提出了一种新的阿贝尔不可压缩流体填充$ν=16$,支持玻色手征$(E_{8})_{1}$共形场论的边缘,是密切相关的拓扑paramagnets在(3+1)D.我们进一步表明,这种拓扑相可以被划分为两个非阿贝尔量子霍尔态填充$ν=8$,每个携带玻色子手性$(G_{2})_{1}$或$(F_{4})_{1}$边缘理论,并托管斐波那契anyonic激发在散装。最后,我们发现了一个新的概念的粒子-空穴共轭的基础上的$E_{8}$状态,联系$G_{2}$和$F_{4}$ Fibonacci状态。

英文摘要:

Through a theoretical coupled wire model, we construct strongly correlated electronic \emph{integer} quantum Hall states. As a distinguishing feature, these states support electric and thermal Hall transport violating the Wiedemann-Franz law as $\left(κ_{xy}/σ_{xy}\right)/\left[\left(π^{2}k_{B}^{2}T\right)/3e^{2}\right]<1$.We propose a new Abelian incompressible fluid at filling $ν=16$ that supports a bosonic chiral $(E_{8})_{1}$ conformal field theory at the edge and is intimately related to topological paramagnets in (3+1)D. We further show that this topological phase can be partitioned into two non-Abelian quantum Hall states at filling $ν=8$, each carrying bosonic chiral $(G_{2})_{1}$ or $(F_{4})_{1}$ edge theories, and hosting Fibonacci anyonic excitations in the bulk. Finally, we discover a new notion of particle-hole conjugation based on the $E_{8}$ state that relates the $G_{2}$ and $F_{4}$ Fibonacci states.
