Effects of electron-electron interaction and spin-orbit coupling on Andreev pair qubits in quantum dot Josephson junctions
Teodor IliÄin, 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…
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…
Variational solution of the superconducting Anderson impurity model and the band-edge singularity phenomena
Teodor IliÄin, 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…
Auxiliary master equation approach to the Anderson-Holstein impurity problem out of equilibrium
D. Werner, R. Žitko, E. Arrigoni
We introduce a method based on auxiliary master equation for solving the problem of an impurity with local electron-electron and electron-phonon interaction embedded between two co…
Incommensurable matter-wave jets in quasi-1D geometry
Tadej MežnarÅ¡iÄ, Rok Žitko, Katja Gosar +5
Matter-wave jets are ejected from a Bose-Einstein condensate subjected to a modulation of the interaction strength. For sufficiently strong modulation additional higher harmonic ma…
