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 Spectroscopy Reveals the Quantum Geometric Tensor of Topological Josephson Matter
Raffael L. Klees, Gianluca Rastelli, Juan Carlos Cuevas +1
Quantization effects due to topological invariants such as Chern numbers have become very relevant in many systems, yet key quantities such as the quantum geometric tensor providin…
Nonequilibrium Andreev bound states population in short superconducting junctions coupled to a resonator
Raffael L. Klees, Gianluca Rastelli, Wolfgang Belzig
Inspired by recent experiments, we study a short superconducting junction of length (coherence length) inserted in a dc-SQUID containing an ancillary Josephson tunnel junc…
