论文摘要
我们表明，由相互作用电子的库仑场创建的双旋转轨道相互作用（PSOI）导致在具有较大RashBA效应的二维材料中出现非常规相关的电子状态。该作用在足够强的PSOI上表现为结构因子的尖峰，表明趋势是形成条纹结构，其空间尺度由库仑排斥和PSOI引起的电子吸引力之间的竞争确定。在PSOI的临界值之上，该系统在此规模上的电荷密度波动方面变得不稳定。
We show that the pair spin-orbit interaction (PSOI) created by the Coulomb fields of interacting electrons leads to the appearance of an unconventional correlated electronic state in two-dimensional materials with the large Rashba effect. The effect manifests itself at sufficiently strong PSOI as a sharp peak in the structure factor, indicating a tendency to form a striped structure with a spatial scale determined by the competition between the Coulomb repulsion and the PSOI-induced attraction of electrons. Above the critical value of PSOI, the system becomes unstable with respect to the charge density fluctuations on this scale.
