Josephson junctions in double nanowires bridged by in-situ deposited superconductors
Alexandros Vekris, Juan Carlos Estrada Saldaña, Thomas Kanne +9
We characterize parallel double quantum dot Josephson junctions based on closely-grown double nanowires bridged by in-situ deposited superconductors. The parallel double dot behavi…

Two-Impurity Yu-Shiba-Rusinov States in Coupled Quantum Dots
J. C. Estrada Saldaña, A. Vekris, R. Žitko +5
Using double quantum dots as the weak link of a Josephson junction, we realize the superconducting analog of the celebrated two-impurity Kondo model. The device shows a cusped curr…

Supercurrent in a double quantum dot
J. C. Estrada Saldaña, A. Vekris, G. Steffensen +5
We demonstrate the Josephson effect in a serial double quantum dot defined in a nanowire with epitaxial superconducting leads. The supercurrent stability diagram adopts a honeycomb…
