Correlations and Coherence at Different Scales (CCDS25)

We discuss role of the correlation effects due to the Coulomb repulsion between electrons of quantum impurities placed on interface of superconductors, focusing on their interplay with the proximity effect. We show how these competing phenomena can be observed under nonequilibrium conditions imposed e.g. by external magnetic fields, gate potentials, periodic driving, etc. Specific examples will be given, both for the conventional and the topologically nontrivial superconducting nanostructures.
