论文摘要
我们提出了一种新的电流驱动的机制,用于在具有狭窄,强杂交电子带的系统中实现明显的等离子体分散性非记录。效果的大小由电子 - 电子相互作用的强度$α$控制,这导致其在Moiré材料中的特别突出,其特征在于$α\ gg 1 $。此外,这种现象在消退兰道阻尼并增加了等离子体寿命的政权中最为明显。这两种效果的协同作用对莫伊尔材料的新型光电应用具有很大的希望。
We propose a new current-driven mechanism for achieving significant plasmon dispersion nonreciprocity in systems with narrow, strongly hybridized electron bands. The magnitude of the effect is controlled by the strength of electron-electron interactions $α$, which leads to its particular prominence in moiré materials, characterized by $α\gg 1$. Moreover, this phenomenon is most evident in the regime where Landau damping is quenched and plasmon lifetime is increased. The synergy of these two effects holds a great promise for novel optoelectronic applications of moiré materials.
