Weyl半金属中分数量子霍尔效应理论

Theory of the fractional quantum Hall effect in Weyl semimetals

Manisha Thakurathi, A. A. Burkov

摘要:

我们发展了一个流体力学场论的三维分数量子霍尔效应,这是最近提出的存在于磁性Weyl半金属,当Weyl节点由强排斥相互作用间隙。这个理论采用BF理论的形式,它包含一种形式和两种形式的规范场,相应地耦合到准粒子和圈激发。它可以看作是二维分数量子霍尔液体的Chern-Simons理论到三维的推广。

英文摘要:

We develop a hydrodynamic field theory of the three-dimensional fractional quantum Hall effect, which was recently proposed to exist in magnetic Weyl semimetals, when the Weyl nodes are gapped by strong repulsive interactions. This theory takes the form of a BF theory, which contains both one-form and two-form gauge fields, coupling to quasiparticle and loop excitations correspondingly. It may be regarded as a generalization of the Chern-Simons theory of two-dimensional fractional quantum Hall liquids to three dimensions.
