摘要：
我们提出了一种用于探测掺杂陈绝缘体和手性超导体的替代实验方案。我们的方法依赖于将目标手性体系与吸附原子自旋耦合。由于衬底的手性，吸附原子自旋预期会以具有非零自旋手性的非共面构型排列。在此，我们针对在任意自旋旋转下保持不变、并与三个携带经典磁矩的吸附原子耦合的手性衬底，获得了具体结果。通过探索所有可及的磁基态，我们确定了在吸附原子复合体上诱导出非零自旋手性的参数区域。我们将该方法应用于谷极化双层石墨烯和$d+id$超导体，发现了定性不同的基态相图。我们的分析表明，吸附原子自旋手性完全编码了衬底手性的性质。
英文摘要：
We propose an alternative experimental protocol for the detection of doped Chern insulators and chiral superconductors. Our approach relies on coupling the target chiral system to adatom spins. Due to the substrate chirality, the adatom spins are expected to order in a noncoplanar configuration with a nonzero spin chirality. Here, we obtain concrete results for chiral substrates which are invariant under arbitrary spin rotations, and are coupled to three adatoms carrying classical moments. By exploring all the accessible magnetic ground states, we identify the regimes in which nonzero spin chirality is induced on the adatom complex. We apply our method to valley-polarized bilayer graphene and $d+id$ superconductors, and find qualitatively different ground state diagrams. Our analysis shows that the adatom spin chirality fully encodes the properties of the substrate chirality.
