The spectrum of a segment of InAs nanowire, confined between two superconducting leads,
was measured as function of gate voltage and superconducting phase difference using a …

Hybrid semiconductor-superconductor systems are interesting melting pots where various
fundamental effects in condensed-matter physics coexist. For example, when a quantum dot …

A simple impurity solver is shown to capture impurity-induced superconducting subgap
states in quantitative agreement with the numerical renormalization group and quantum …

We theoretically explore the possibility of realizing the symmetry-protected topological
Haldane phase of spin-1 chains in a tunable hybrid platform of superconducting islands …

We study the in-gap states of a quantum dot hybridized with one conducting and another
superconducting electrode. The proximity effect suppresses the electronic states in the entire …

Self-consistent perturbation expansion up to the second order in the interaction strength is
used to study a single-level quantum dot with local Coulomb repulsion attached …

We derive and apply a general scheme for mapping a setup consisting of a half-filled single-
level quantum dot coupled to one normal metallic and two superconducting phase-biased …

Time-reversal-invariant topological superconducting (TRITOPS) wires are known to host a
fractional spin ℏ/4 at their ends. We investigate how this fractional spin affects the …

We study the Anderson single-level quantum dot attached to two BCS superconducting
leads with the same gap size. We reveal that a system with asymmetric tunnel coupling to …

Connecting two half-filled quantum dots to two superconducting leads induces a competition
of bonds, with the dots forming either an interdot exchange bond or two individual Yu-Shiba …
