Tunneling processes between Yu-Shiba-Rusinov bound states
A. Villas, R. L. Klees, G. Morrás +5
Very recent experiments have reported the tunneling between Yu-Shiba-Rusinov (YSR) bound states at the atomic scale. These experiments have been realized with the help of a scannin…
Second Chern Number and Non-Abelian Berry Phase in Topological Superconducting Systems
H. Weisbrich, R. L. Klees, G. Rastelli +1
Topology ultimately unveils the roots of the perfect quantization observed in complex systems. The 2D quantum Hall effect is the celebrated archetype. Remarkably, topology can mani…
Interplay Between Yu-Shiba-Rusinov States and Multiple Andreev Reflections
Alberto Villas, Raffael L. Klees, Haonan Huang +4
Motivated by recent scanning tunneling microscopy experiments on single magnetic impurities on superconducting surfaces, we present here a comprehensive theoretical study of the in…
Microwave signatures of Majorana states in a topological Josephson junction
Jukka I. Väyrynen, Gianluca Rastelli, Wolfgang Belzig +1
We find the admittance of a topological Josephson junction as a function of frequency , the static phase bias applied to the superconducting leads, and tempe…
Quantum phase-slips in Josephson junction rings
G. Rastelli, I. M. Pop, F. W. J. Hekking
We study quantum phase-slip (QPS) processes in a superconducting ring containing N Josephson junctions and threaded by an external static magnetic flux. In a such system, a QPS con…
