Double nanowires for hybrid quantum devices
Thomas Kanne, Dags Olsteins, Mikelis Marnauza +8
Parallel one-dimensional semiconductor channels connected by a superconducting strip constitute the core platform in several recent quantum device proposals that rely e.g. on Andre…
Temperature Induced Shifts of Yu-Shiba-Rusinov Resonances in Nanowire-Based Hybrid Quantum Dots
Juan Carlos Estrada Saldaña, Alexandros Vekris, Victoria Sosnovtseva +4
The strong coupling of a superconductor to a spinful quantum dot results in Yu-Shiba-Rusinov (YSR) discrete subgap excitations. In isolation and at zero temperature, the excitation…
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…
