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 (YSR …

Connecting double quantum dots via a semiconductor-superconductor hybrid segment
offers a platform for creating a two-site Kitaev chain that hosts Majorana zero modes at a …

We combine scanning-tunneling-spectroscopy experiments probing magnetic impurities on
a superconducting surface with a theoretical analysis of the tunneling processes between …

Magnetic adatom chains on surfaces constitute fascinating quantum spin systems.
Superconducting substrates suppress interactions with bulk electronic excitations but couple …

A magnetic atom inside a superconductor locally distorts superconductivity. It scatters
Cooper pairs as a potential with broken time-reversal symmetry, leading to localized bound …

Theoretical descriptions of Yu-Shiba-Rusinov (YSR) states induced by magnetic impurities
inside the gap of a superconductor typically rely on a classical spin model or are restricted to …

Coupling individual atoms fundamentally changes the state of matter: electrons bound to
atomic cores become delocalized turning an insulating state to a metallic one. A chain of …

Magnetic adatoms on superconductors give rise to Yu-Shiba-Rusinov (YSR) states that hold
considerable interest for the design of topological superconductivity. Here, we show that …

We show that the magnetic ordering of coupled atomic dimers on a superconductor is
revealed by their intragap spectral features. Chromium atoms on the superconductor β-Bi 2 …

Magnetic adsorbates on superconductors induce local bound states within the
superconducting gap. These Yu-Shiba-Rusinov (YSR) states decay slowly away from the …
