Quasiparticle-resolved variational theory of Andreev spin qubits
Teodor Iličin, Rok Žitko
An Andreev spin qubit stores a single unpaired spin, yet its coupling to the superconducting phase can be dominated by coherent virtual quasiparticle pairs. We develop a continuum…
Strongly correlated Josephson junction: proximity effect in the single-layer Hubbard model
Don Rolih, Rok Žitko
We study the proximity effect in the Hubbard model coupled to BCS superconductors describing a single-layer strongly correlated electron system in a phase-biased Josephson junction…
Effects of electron-electron interaction and spin-orbit coupling on Andreev pair qubits in quantum dot Josephson junctions
Teodor Iličin, Rok Žitko
We investigate the superconducting Anderson impurity model for interacting quantum dot Josephson junctions with spin-orbit coupling and a term accounting for tunnelling through hig…
Variational solution of the superconducting Anderson impurity model and the band-edge singularity phenomena
Teodor Iličin, Rok Žitko
We propose a set of variational wavefunctions for the sub-gap spin-doublet and spin-singlet eigenstates of the particle-hole symmetric superconducting Anderson impurity model. The…
Higher order spin interactions mediated by the substrate
Szczepan Głodzik, Rok Žitko
Since the seminal works in the fifties it has been known that a bath of non-interacting electrons mediates an interaction between local moments (such as nuclear spins or magnetic i…
Inelastic tunneling through normal and superconducting junctions in the presence of photonic bath within Lindbladian formalism
Ádám Bácsi, Rok Žitko
An electron tunneling across a junction integrated into an electric circuit can generate an excitation in the photonic field (electromagnetic environment) and lose energy in the pr…
