Rare-earth atoms on Nb(110) as a platform to engineer topological superconductivity
David Antognini Silva, Yu Wang, Nicolae Atodiresei +5
Helical spin textures in one-dimensional magnetic chains on superconductors can enable topological superconductivity and host Majorana zero modes, independent of the presence of in…
Observation of zero-energy modes in Gd atomic chains on superconducting Nb(110)
Yu Wang, Felix Friedrich, Matthias Bode +1
In this experimental study, we use scanning tunneling microscopy and spectroscopy to investigate Yu-Shiba-Rusinov states induced by 4f-shell rare-earth Gd adatoms on a superconduct…
Spin-resolved spectroscopic evidence for spinarons in Co adatoms
Felix Friedrich, Artem Odobesko, Juba Bouaziz +2
Single cobalt atoms on the (111) surfaces of noble metals were for a long time considered prototypical systems for the Kondo effect in scanning tunneling microscopy experiments. Ye…
Boosting the STM's spatial and energy resolution with double-functionalized probe tips
Artem Odobesko, Raffael L. Klees, Felix Friedrich +2
Scattering of superconducting pairs by magnetic impurities on a superconducting surface leads to pairs of sharp in-gap resonances, known as Yu-Shiba-Rusinov (YSR) bound states. Sim…
Coupling of Yu-Shiba-Rusinov states in 1D chains of Fe atoms on Nb(110)
Felix Friedrich, Robin Boshuis, Matthias Bode +1
The hybridization of Yu-Shiba-Rusinov states in dimers of magnetic impurities leads to molecular-like bonding and antibonding modes. In many-impurity systems, the interaction gives…
Anisotropic vortices on superconducting Nb(110)
Artem Odobesko, Felix Friedrich, Song-Bo Zhang +4
We investigate the electronic properties of type-II superconducting Nb(110) in an external magnetic field. Scanning tunneling spectroscopy reveals a complex vortex shape which deve…
Observation of tunable single-atom Yu-Shiba-Rusinov states
Artem Odobesko, D. Di Sante, A. Kowalski +5
The coupling of a spin to an underlying substrate is the basis for a plethora of phenomena. In the case of a metallic substrate, Kondo screening of the adatom magnetic moment can o…
Onset of phase diffusion in high kinetic inductance granular aluminum micro-SQUIDs
Felix Friedrich, Patrick Winkel, Kiril Borisov +4
Superconducting granular aluminum is attracting increasing interest due to its high kinetic inductance and low dissipation, favoring its use in kinetic inductance particle detector…
Circuit Quantum Electrodynamics of Granular Aluminum Resonators
N. Maleeva, L. Grünhaupt, T. Klein +12
The introduction of crystalline defects or dopants can give rise to so-called "dirty superconductors", characterized by reduced coherence length and quasiparticle mean free path. I…
