Interfering tunneling paths through magnetic molecules on superconductors: Asymmetries of Kondo and Yu-Shiba-Rusinov resonances
Laëtitia Farinacci, Gelavizh Ahmadi, Michael Ruby +5
Magnetic adsorbates on superconductors induce a Kondo resonance outside and Yu-Shiba-Rusinov (YSR) bound states inside the superconducting energy gap. When probed by scanning tunne…
Tuning the coupling of an individual magnetic impurity to a superconductor: quantum phase transition and transport
Laëtitia Farinacci, Gelavizh Ahmadi, Gaël Reecht +6
The exchange scattering at magnetic adsorbates on superconductors gives rise to Yu-Shiba-Rusinov (YSR) bound states. Depending on the strength of the exchange coupling, the magneti…
Wave-function hybridization in Yu-Shiba-Rusinov dimers
Michael Ruby, Benjamin W. Heinrich, Yang Peng +2
Magnetic adsorbates on superconductors induce local bound states within the superconducting gap. These Yu-Shiba-Rusinov (\YSR) states decay slowly away from the impurity compared t…
Exploring a proximity-coupled Co chain on Pb(110) as a possible Majorana platform
Michael Ruby, Benjamin W. Heinrich, Yang Peng +2
Linear, suspended chains of magnetic atoms proximity coupled to an s-wave superconductor are predicted to host Majorana zero modes at the chain ends in the presence of strong spin-…
Orbital Picture of Yu-Shiba-Rusinov Multiplets
Michael Ruby, Yang Peng, Felix von Oppen +2
We investigate the nature of Yu-Shiba-Rusinov (YSR) subgap states induced by single Manganese (Mn) atoms adsorbed on different surface orientations of superconducting lead (Pb). De…
Magnetic anisotropy in Shiba bound states across a quantum phase transition
Nino Hatter, Benjamin W. Heinrich, Michael Ruby +2
The exchange coupling between magnetic adsorbates and a superconducting substrate leads to Shiba states inside the superconducting energy gap and a Kondo resonance outside the gap.…
End states and subgap structure in proximity-coupled chains of magnetic adatoms
Michael Ruby, Falko Pientka, Yang Peng +3
A recent experiment [Nadj-Perge et al., Science 346, 602 (2014)] provides evidence for Majorana zero modes in iron (Fe) chains on the superconducting Pb(110) surface. Here, we stud…
Tunneling processes into localized subgap states in superconductors
Michael Ruby, Falko Pientka, Yang Peng +3
We combine scanning-tunneling-spectroscopy experiments probing magnetic impurities on a superconducting surface with a theoretical analysis of the tunneling processes between (supe…
Experimental demonstration of a two-band superconducting state for lead using scanning tunneling spectroscopy
Michael Ruby, Benjamin W. Heinrich, Jose I. Pascual +1
The type I superconductor lead (Pb) has been theoretically predicted to be a two-band superconductor. We use scanning tunneling spectroscopy (STS) to resolve two superconducting ga…
