Abstract In a recent paper, we theoretically investigated the density of states of the composite channel–contact system in the Coulomb and Kondo regimes using the self-consistent field approximation. There are the main experimental observations of vibration features in the Coulomb blockade [H. Park et al., Nature (London) 407, 57 (2000)] and Kondo [L. H. Yu et al., Phys. Rev. Lett. 93, 266802 (2004)] regimes. In the Kondo regime, our results show that one peak at E = μ can be observed in the density of states at low temperatures (0.0026 eV ≤ kBT ≤ 0.0000026 eV). Also, the real part of ∑3 has one minimum peak at E = − μ and the real par of ∑2 has one maximum peak at E = − μ for 0.01 ≤ μ ≤ 0.07 in the Kondo regime at low temperatures.
