  Electron tunneling through quantum-dots side coupled to a quantum wire, in
equilibrium and nonequilibrium Kondo regime, is studied. The mean-field
finite-$U$ slave-boson formalism is used to obtain the solution of the problem.
We have found that the transmission spectrum shows a structure with two
anti-resonances localized at the renormalized energies of the quantum dots. The
DOS of the system shows that when the Kondo correlations are dominant there are
two Kondo regimes with its own Kondo temperature. The above behavior of the DOS
can be explained by quantum interference in the transmission through the two
different resonance states of the quantum dots coupled to common leads. This
result is analogous to the Dicke effect in optics. We investigate the many body
Kondo states as a function of the parameters of the system.
