Generalized transmon Hamiltonian for Andreev spin qubits
Luka Pavešić, Rok Žitko
We solve the problem of an interacting quantum dot embedded in a Josephson junction between two superconductors with finite charging energy described by the transmon (Cooper pair b…
Exchange interaction between two quantum dots coupled through a superconducting island
Ádám Bácsi, Luka Pavešić, Rok Žitko
We present a theoretical study of a system consisting of a superconducting island and two quantum dots, a possible platform for building qubits and Cooper pair splitters, in the re…
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…
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…
Subgap states in superconducting islands
Luka Pavešić, Daniel Bauernfeind, Rok Žitko
We study an interacting quantum dot in contact with a superconducting island described by the Richardson model with a Coulomb repulsion term controlling the number of electrons on…
