Phonons and electron-phonon coupling from density functional perturbation theory (DFPT)

Malgorzata Wierzbowska

This is an introduction to phonons and electron-phonon couplings. I will explain how to get those quantities from perturbed density functional theory. Later I give computational detail in the framework of plane-wave pseudopotential code (PWSCF). The application in superconductivity is planned for future seminar.
