Magnetic Impurities on Superconducting Surfaces: Phase Transitions and the Role of Impurity-Substrate Hybridization
Haonan Huang, Robert Drost, Jacob Senkpiel +7
Spin-dependent scattering from magnetic impurities inside a superconductor gives rise to Yu-Shiba-Rusinov (YSR) states within the superconducting gap. As such, YSR states have been…
Dynamical Coulomb Blockade as a Local Probe for Quantum Transport
Jacob Senkpiel, Jan C. Klöckner, Markus Etzkorn +9
Quantum fluctuations are imprinted with valuable information about transport processes. Experimental access to this information is possible, but challenging. We introduce the dynam…
Single Channel Josephson Effect in a High Transmission Atomic Contact
Jacob Senkpiel, Simon Dambach, Markus Etzkorn +9
The Josephson effect in scanning tunneling microscopy (STM) is an excellent tool to probe the properties of the superconducting order parameter on a local scale through the Ambegao…
Robustness of Yu-Shiba-Rusinov resonances in presence of a complex superconducting order parameter
Jacob Senkpiel, Carmen Rubio-Verdú, Markus Etzkorn +8
Robust quantum systems rely on having a protective environment with minimized relaxation channels. Superconducting gaps play an important role in the design of such environments. T…
Signatures of phase-coherent transport and the role of quantum fluctuations in the dynamical Coulomb blockade regime
Berthold Jäck, Jacob Senkpiel, Markus Etzkorn +3
Josephson junctions operated in the dynamical Coulomb blockade regime recently gained an significant amount of attention as central building block in concepts to demonstrate the no…
