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…
Correlation of Vibrational Excitations and Electronic Structure\\ with Submolecular Resolution
Daniela Rolf, Friedrich Maass, Christian Lotze +4
The detection of vibrational excitations of individual molecules on surfaces by scanning tunneling spectroscopy does not obey strict selection rules but rather propensity rules. Th…
Yu-Shiba-Rusinov states in the charge-density modulated superconductor NbSe2
Eva Liebhaber, Sergio Acero Gonzalez, Rojhat Baba +6
NbSe is a remarkable superconductor in which charge-density order coexists with pairing correlations at low temperatures. Here, we study the interplay of magnetic adatoms and t…
Visualizing Intramolecular Distortions as the Origin of Transverse Magnetic Anisotropy
Daniela Rolf, Christian Lotze, Constantin Czekelius +2
The magnetic properties of metal-organic complexes are strongly influenced by conformational changes in the ligand. The flexibility of Fe-tetra-pyridyl-porphyrin molecules leads to…
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…
Control of oxidation and spin state in a single-molecule junction
Benjamin W. Heinrich, Christopher Ehlert, Nino Hatter +4
The oxidation and spin state of a metal-organic molecule determine its chemical reactivity and magnetic properties. Here, we demonstrate the reversible control of the oxidation and…
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…
Scaling of Yu-Shiba-Rusinov energies in the weak-coupling Kondo regime
Nino Hatter, Benjamin W. Heinrich, Daniela Rolf +1
The competition of the free spin state of a paramagnetic impurity on a superconductor with its screened counterpart is characterized by the energy scale of Kondo screening …
Single magnetic adsorbates on s-wave superconductors
Benjamin W. Heinrich, Jose I. Pascual, Katharina J. Franke
In superconductors, magnetic impurities induce a pair-breaking potential for Cooper pairs, which locally affects the Bogoliubov quasiparticles and gives rise to Yu-Shiba-Rusinov (Y…
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-…

Gaël Reecht, Benjamin Heinrich, Hervé Bulou +3
We present an improved way for imaging the local density of states with a scanning tunneling microscope, which consists in mapping the surface topography while keeping the differen…

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.…
