Abstract :
Electron tunneling through a double quantum-dot molecule side attached to a quantum wire, in the Kondo regime, is studied. The mean-field finite-U slave-boson formalism is used to obtain the solution of the problem. We found conductance cancellations when the molecular energies of the side attached double quantum-dot cross the Fermi energy. We investigate the many body molecular Kondo states and its interplay with the inter-dot antiferromagnetic correlation as a function of the parameters of the system.
