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, my …

Formalism for describing electron-phonon scattering, surface scattering, and spin relaxation is dervied for the Keldysh non-equilibrium Green's functions (NEGF) method. Approximation useful for …
Sign of imaginary part of self-energy for hole Hamiltonian
Prof Datta in his QTAT Exercise Ch8, discusses that the imaginary part of the contact self-energy should be negative while the real part will tend towards zero for large energies in both directions. …
