  1. How to consider electron-photon interaction w/o using self-energy?

    Closed | Responses: 0

    Hi, In negf, interactions are considered as self-energies. For electron-photon interaction, a perturbation Hamiltonian is derived and then self-energy is found using coupled-field theory. Now,...
