Kondo resonances in an Aharonov-Bohm ring with an in-line quantum dot

The properties of the ground state of a closed dot‐ring system with a magnetic flux in the Kondo regime are studied theoretically by means of a one‐impurity Anderson Hamiltonian. The Hamiltonian is solved by means of the slave‐boson mean‐field theory. It is shown that at T = 0, a suppressed Kondo ef...
