We have studied the Kondo quantum dot coupled to two superconducting
leads and investigated the subgap Andreev states
using the NRG method. Contrary to the recent NCA results, we observe
Andreev states both below and above the Fermi level.
In the framework of the slave-rotor theory, we also reexamine the system.
Coffee and cookies will be served 15 minutes before the start of the seminar
