First-principles theory of nonlinear long-range electron-phonon interaction
Matthew Houtput, Luigi Ranalli, Carla Verdi +4
Describing electron-phonon interactions in a solid requires knowledge of the electron-phonon matrix elements in the Hamiltonian. State-of-the-art first-principles calculations for…
