论文摘要
我们提出了一个理论，该理论是由经过定期驾驶的二维（2D）电子系统介导的介导的介导的相互作用的理论。这是针对由两个侧向夹有2D金属垫片组成的异质结构的。我们的计算揭示了自旋敏感性中的新非分析特征。对于弱点耦合，rkky相互作用显示出可通过光振幅和频率调整的周期。为了更强的轻度耦合，相互作用变为非振荡，并且保持纯粹的铁磁。
We present a theory for the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction mediated by a two-dimensional (2D) electron system subjected to periodic driving. This is demonstrated for a heterostructure consisting of two ferromagnets laterally sandwiching the 2D metallic spacer. Our calculations reveal new non-analytic features in the spin susceptibility. For weak light-matter coupling, the RKKY interaction shows oscillations with a period tunable by the light amplitude and frequency. For stronger light-matter coupling, the interaction becomes non-oscillatory and remains purely ferromagnetic.
