论文摘要
从理论上讲，我们研究了ruderman-kittel-kasuya-yosida（rkky）在两个磁性杂质之间的交换相互作用的特征，这些磁杂质在域壁（DW）内的界面结合状态介导。后者在石墨烯和Weyl Semimetal中具有相反签名的反转对称性术语，将两个区域分开。 DW由平滑的量子孔建模，该量子井携带许多离散的结合状态，包括一对具有相反手性的无间隙，金属零能量模式。我们发现这些界面性手性结合状态在自旋反应（rkky交换相互作用）中的明确特征，这对量子良好的变形是可靠的。
We theoretically investigate the features of Ruderman-Kittel-Kasuya-Yosida (RKKY) exchange interaction between two magnetic impurities, mediated by the interfacial bound states inside a domain wall (DW). The latter separates the two regions with oppositely signed inversion symmetry broken terms in graphene and Weyl semimetal. The DW is modelled by a smooth quantum well which hosts a number of discrete bound states including a pair of gapless, metallic zero-energy modes with opposite chiralities. We find clear signatures of these interfacial chiral bound states in spin response (RKKY exchange interaction) which is robust to the deformation of the quantum well.
