26. To speak exactly, the renormalized levels εj have very minimal deviations from the Fermi level. Such deviations ensure a nonzero renormalization parameter bj. The nonzero bj leads to a finite broadening of the Kondo peaks in the density of states, as seen in Fig. 2. However, because the deviations are very small, the line shape of the density of states of the two QDs shown in Fig. 2 looks almost symmetric with respect to the Fermi level. Usually, the Kondo resonance is viewed as to occur at Fermi level in equilibrium, without mention of the minimal deviation. This argument can also be found in previous works where the SBMFA was employed, e.g., B. H. Wu, J. C. Cao, and K. H. Ahn, Phys. Rev. B PRBMDO 0163-1829 10.1103/PhysRevB.72.165313 72, 165313 (2005);
