Diagrammatic perturbation technique for a quantum dot connected to superconducting leads
Original language description
We study the spectral properties of a quantum dot embedded between two superconductors showing a phase difference. The system is described as a single-impurity Anderson model coupled to BCS superconducting leads. We utilize diagrammatic perturbation techniques in the Coulomb interaction to capture the relevant physical phenomena, particularly the effect of Coulomb interaction on the Andreev bound states present in the electronic spectrum. Results of the Hartree - Fock approximation and the random phaseapproximation at zero temperature are presented.
