Theoretical issues in the accurate computation of the electron-phonon interaction contribution to the total energy
Shilpa Paul, M. P. Gururajan, Amrita Bhattacharya +1
We report the computation of the Standard Hamiltonian of a coupled electron-phonon system by accurately computing the electron-phonon interaction (EPI) contribution to the total en…
