Yu-Shiba-Rusinov states in color superconducting quark matter
Virgil V. Baran, Jens Paaske
The high-density region of the QCD phase diagram displays an intricate competition between color superconductivity and the QCD Kondo effect due to color exchange in quark matter co…

The poor man's Majorana tetron
Maximilian Nitsch, Lorenzo Maffi, Virgil V. Baran +4
The Majorana tetron is a prototypical topological qubit stemming from the ground state degeneracy of a superconducting island hosting four Majorana modes. This degeneracy manifests…

Majorana modes in quantum dots coupled via a floating superconducting island
R. Seoane Souto, V. V. Baran, M. Nitsch +4
Majorana modes can be engineered in arrays where quantum dots (QDs) are coupled via grounded superconductors, effectively realizing an artificial Kitaev chain. Minimal Kitaev chain…
