Parity anomaly and spin transmutation in quantum spin Hall Josephson junctions
Yang Peng, Yuval Vinkler-Aviv, Piet W. Brouwer +2
We study the Josephson effect in a quantum spin Hall system coupled to a localized magnetic impurity. As a consequence of the fermion parity anomaly, the spin of the combined syste…
Negative permittivity attests to local attractive interactions in bubble and stripe phases
Benedikt Friess, Yang Peng, Bernd Rosenow +4
The physics of itinerant electrons in condensed matter is by and large governed by repulsive Coulomb forces. However, rare cases exist where local attractive interactions emerge an…
Orbital Picture of Yu-Shiba-Rusinov Multiplets
Michael Ruby, Yang Peng, Felix von Oppen +2
We investigate the nature of Yu-Shiba-Rusinov (YSR) subgap states induced by single Manganese (Mn) atoms adsorbed on different surface orientations of superconducting lead (Pb). De…
Strong localization of Majorana end states in chains of magnetic adatoms
Yang Peng, Falko Pientka, Leonid I. Glazman +1
A recent experiment [Nadj-Perge et al., Science 346, 602 (2014)] gives possible evidence for Majorana bound states in chains of magnetic adatoms placed on a superconductor. While m…
A quantum reactive scattering perspective on electronic nonadiabaticity
Yang Peng, Luca M. Ghiringhelli, Heiko Appel
Based on quantum reactive-scattering theory, we propose a method for studying the electronic nonadiabaticity in collision processes involving electron-ion rearrangements. We invest…
