Magnetic texture modulated superconductivity in superconductor/ferromagnet shells of semiconductor nanowires
Nabhanila Nandi, Juan Carlos Estrada Saldaña, Alexandros Vekris +11
In a one-dimensional ferromagnet-superconductor nanowire, magnetism can suppress superconductivity except where the Zeeman field is suppressed, for example domain wall superconduct…
Synthetic spin-orbit coupling in superconductor-semiconductor hybrid nanowires with micromagnet arrays
M. P. Hynes, D. Burke, K. Ganesh +9
Spin-orbit interaction accounts for the coupling of momentum and spin degrees of freedom of electrons and holes in semiconductor materials. In quantum information processing, it al…
Richardson model with complex level structure and spin-orbit coupling for hybrid superconducting islands: stepwise suppression of pairing and magnetic pinning
Juan Carlos Estrada Saldaña, Luka Pavešič, Alexandros Vekris +3
An epitaxial semiconductor-superconductor nanowire is a superconducting system with a complex level structure originating from hybridization: in addition to a dense set of higher-e…
Electronic transport in double-nanowire superconducting islands with multiple terminals
Alexandros Vekris, Juan Carlos Estrada Saldaña, Thomas Kanne +7
We characterize in-situ grown parallel nanowires bridged by a superconducting island. The magnetic-field and temperature dependence of Coulomb blockade peaks measured across differ…
Entanglement between quasiparticles in superconducting islands mediated by a single spin
Juan Carlos Estrada Saldaña, Alexandros Vekris, Luka Pavešič +3
Condensed matter is composed of a small set of identical units, yet it shows an immense range of behaviour. Recently, an array of cold atoms was used to generate long-range quantum…
Asymmetric Little-Parks Oscillations in Full Shell Double Nanowires
Alexandros Vekris, Juan Carlos Estrada Saldaña, Joeri de Bruijckere +6
Little-Parks oscillations of a hollow superconducting cylinder are of interest for flux-driven topological superconductivity in single Rashba nanowires. The oscillations are typica…
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…
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…
Excitations in a superconducting Coulombic energy gap
Juan Carlos Estrada Saldaña, Alexandros Vekris, Luka Pavešič +4
Cooper pairing and Coulomb repulsion are antagonists, producing distinct energy gaps in superconductors and Mott insulators. When a superconductor exchanges unpaired electrons with…
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…
