分数量子化霍尔效应的有效场论

Effective Field Theory of Fractional Quantized Hall Nematics

Michael Mulligan, Chetan Nayak, Shamit Kachru

摘要:

我们提出了分数量子化霍尔霍尔态的Landau-Ginzburg理论以及从各向同性分数量子霍尔态到它的跃迁。这证明了Lifshitz-Chern-Simons理论-这被证明是它的对偶-在更微观的基础上,使我们能够计算基态波函数在破缺阶段。在这种物质状态下,霍尔电阻保持量子化,而由于热激发准粒子的纵向直流电阻率是各向异性的。用我们的理论解释了最近在朗道能级填充因子ν=7/3时的实验。

英文摘要:

We present a Landau-Ginzburg theory for a fractional quantized Hall nematic state and the transition to it from an isotropic fractional quantum Hall state. This justifies Lifshitz-Chern-Simons theory -- which is shown to be its dual -- on a more microscopic basis and enables us to compute a ground state wave function in the symmetry-broken phase. In such a state of matter, the Hall resistance remains quantized while the longitudinal DC resistivity due to thermally-excited quasiparticles is anisotropic. We interpret recent experiments at Landau level filling factor ν=7/3 in terms of our theory.
