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…
Probing chiral symmetry with a topological domain wall sensor
Glenn Wagner, Titus Neupert, Ronny Thomale +5
Chiral symmetry is a fundamental property with profound implications for the properties of elementary particles, that implies a spectral symmetry (i.e. E => -E ) in their dispersio…
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…
Interaction effects in a 1D flat band at a topological crystalline step edge
Glenn Wagner, Souvik Das, Johannes Jung +11
Step edges of topological crystalline insulators can be viewed as predecessors of higher-order topology, as they embody one-dimensional edge channels embedded in an effective three…
A Systematic Investigation of the Coupling between One-Dimensional Edge States of a Topological Crystalline Insulator
Johannes Jung, Artem Odobesko, Robin Boshuis +3
The interaction of spin-polarized one-dimensional (1D) topological edge modes localized along single-atomic steps of the topological crystalline insulator …
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…
On the preparation and electronic properties of clean superconducting Nb(110) surfaces
Artem B. Odobesko, Soumyajyoti Haldar, Stefan Wilfert +7
We have studied cleaning procedures of Nb(110) by verifying the surface quality with low-energy electron diffraction, Auger electron spectroscopy, and scanning tunneling microscopy…
Breaking crystalline symmetry of epitaxial SnTe films by strain
Steffen Schreyeck, Karl Brunner, Laurens W. Molenkamp +7
SnTe belongs to the recently discovered class of topological crystalline insulators. Here we study the formation of line defects which break crystalline symmetry by strain in thin…
