论文摘要
数十年来，已经积极研究了二维（2D）电子系统中的相互作用和混乱的相互作用。范式方法涉及从干净的费米液体开始，并通过障碍和相互作用扰动系统。相反，我们从2D铁磁量子临界点附近的清洁非纤维液体开始，并考虑疾病的影响。与无序的费米液体相反，我们发现我们的模型不会遭受失控的流向强耦合，并且该系统具有略有稳定的固定点，并具有完美的传导。
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.
