dc.description.abstract | We study a strongly interacting quantum dot connected to a normal and to a superconducting lead. By means of the slave-boson technique we investigate the low-temperature regime and discuss electrical transport through the dot. At the level of mean-field approximation we are able to discuss both limits of small and large Δ/TK, where Δ is the superconducting gap and TK is the Kondo temperature. We also find that the zero-bias anomaly in the current-voltage characteristics, which is associated with the occurrence of the Kondo resonance in the quantum dot, is enhanced in the presence of superconductivity, due to resonant Andreev scattering. | en |
