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 equilibr...
