Interplay between pairing and correlations in spin-polarized bound states
We investigate the single and multiple defects embedded in a superconducting
host, studying interplay between the proximity induced pairing and
interactions. We explore influence of the spin-orbit coupling on energies,
polarization and spatial patterns of the bound (Yu-Shiba-Rusinov) states of
magnetic impurities in 2-dimensional square lattice. We also address the
peculiar bound states in the proximitized Rashba chain, resembling the Majorana
quasiparticles, focusing on their magnetic polarization which has been recently
reported by S. Jeon et al., [Science 358, 772 (2017)]. Finally, we study
leakage of these polarized Majorana quasiparticles on the side-attached
nanoscopic regions and confront them with the subgap Kondo effect near to the
singlet-doublet phase transition.Comment: 10 pages, 9 figure
