Mapping of Yu-Shiba-Rusinov states from an extended scatterer
Markus Etzkorn, Matthias Eltschka, Berthold Jäck +2
We investigate the spatial evolution of Yu-Shiba-Rusinov (YSR) states resulting from the interaction between Copper phthalocyanine molecules and a superconducting Vanadium (100) su…

Critical Josephson current in the dynamical Coulomb blockade regime
Berthold Jäck, Matthias Eltschka, Maximilian Assig +3
Superconductivity is commonly described as a macroscopic quantum phenomenon. However, it arises from microscopic mechanisms occurring at the nanometer scale as illustrated, for exa…

The energy resolution function of a tunnel junction
Christian R. Ast, Berthold Jäck, Jacob Senkpiel +4
The tunnel junction between tip and sample in a scanning tunneling microscope is an ideal platform to access the local density of states in the sample through the differential cond…
