Nonequilibrium perturbative formalism and spectral function for the Anderson model
The present work is based on the nonequilibrium perturbative formalism. There the self-energies are derived up to the fourth-order. Consequently, it proves that the nonequilibrium (real-time) perturbative expansion can be connected with the Matsubara imaginary-time perturbative expansion for equil...

| description |
The present work is based on the nonequilibrium perturbative formalism. There the self-energies are derived
up to the fourth-order. Consequently, it proves that the nonequilibrium (real-time) perturbative expansion can
be connected with the Matsubara imaginary-time perturbative expansion for equilibrium. As the numerical
results, the Kondo resonance still disappears for bias voltage exceeding the Kondo temperatures, as observed
in experiments of two terminal systems. |
