Using the self-consistent second-order perturbation expansion, it is demonstrated that although the parity effect indeed appears generically, the shape of the spectrum exhibits nonuniversal properties depending on a model system employed, in contrast to the previous study of Thimm et al. In the nonequilibrium case, the oscillation behavior possesses the parity effect in the differential conductance 关键词: Kondo effect;magnetic impurities;nanostructured materials;perturbation theory;parity effects;nanoscale metallic grain;magnetic impurity;Kondo effect;self-consistent second-order perturbation expansion;nonequilibrium case;oscillation behavior;differential conductance
