二维无序非费米液体中相互作用诱导的金属丰度

Interaction-induced metallicity in a two-dimensional disordered non-Fermi liquid

P. A. Nosov, I. S. Burmistrov, S. Raghu

摘要:

二维(2D)电子系统中相互作用和无序的相互作用已经被积极研究了几十年。典型的方法包括从一个干净的费米液体开始,用无序和相互作用来扰动系统。相反,我们从一个干净的非费米液体附近的二维铁磁量子临界点,并考虑无序的影响。与无序费米液体相比,我们发现,我们的模型不会遭受失控流强耦合和系统有一个边缘稳定的固定点与完美的传导。

英文摘要:

The interplay of interactions and disorder in two-dimensional (2D) electron systems has actively been studied for decades. The paradigmatic approach involves starting with a clean Fermi liquid and perturbing the system with both disorder and interactions. We instead start with a clean non-Fermi liquid near a 2D ferromagnetic quantum critical point and consider the effects of disorder. In contrast with the disordered Fermi liquid, we find that our model does not suffer from runaway flows to strong coupling and the system has a marginally stable fixed point with perfect conduction.
