We investigate single and multiple defects embedded in a superconducting host, studying the interplay between the proximity-induced pairing and interactions. We explore the influence of the spin-orbit coupling on energies, polarization and spatial patterns of the bound (Yu-Shiba-Rusinov) states of magnetic impurities in a two-dimensional square lattice. We also address the peculiar bound states in the proximitized Rashba chain, resembling the Majorana quasiparticles, focusing on their magnetic polarization that has been recently reported by S. Jeon et al. ( 772). Finally, we study leakage of these polarized Majorana quasiparticles into side-attached nanoscopic regions and confront them with the subgap Kondo effect near to the singlet-doublet phase transition.
我们研究了嵌入超导主体中的单个和多个缺陷，探讨了近邻诱导配对与相互作用之间的相互影响。我们探究了自旋轨道耦合对二维方形晶格中磁性杂质的束缚（汤浅-芝-鲁西诺夫）态的能量、极化和空间模式的影响。我们还研究了近邻化的 Rashba 链中类似于马约拉纳准粒子的奇特束缚态，重点关注 S. Jeon 等人（772）最近报道的它们的磁极化。最后，我们研究了这些极化的马约拉纳准粒子向侧面附着的纳米区域的泄漏情况，并将其与单重态-双重态相变附近的亚能隙近藤效应进行对比。
