We explore the physics of novel fermion liquids emerging from conducting networks, where 1D metallic wires form a periodic 2D superstructure. Such structure naturally appears in marginally twisted bilayer graphenes, moire transition metal dichalcogenides, and also in some charge-density wave materials. For these network systems, we theoretically show that a remarkably wide variety of new non-Fermi-liquids emerge and that these non-Fermi-liquids can be classified by the characteristics of the junctions in networks. Using this, we calculate the electric conductivity of the non-Fermi-liquids as a function of temperature, which show markedly different scaling behaviors than a regular 2D Fermi liquid.

传导二维网络的非费米液体

我们探索了从导电网络中出现的新型费米液体的物理原理，其中一维金属线形成了周期性的二维上层建筑。这种结构自然地出现在略微扭曲的双层石墨烯，莫尔过渡金属二卤化物以及某些电荷密度波材料中。对于这些网络系统，我们从理论上证明，出现了大量新的非费米液体，并且这些非费米液体可以通过网络中结的特征进行分类。使用此方法，我们计算出非费米液体的电导率随温度的变化，与常规的二维费米液体相比，它们的结垢行为明显不同。
