LINEAR-RESPONSE CALCULATIONS OF ELECTRON-PHONON INTERACTIONS

A new, generally applicable method is developed for ab initio calculation of the wave-vector dependent electron-phonon coupling. The screening of the one-electron potential is evaluated by linear-response theory using the local-density approximation and linear muffin-tin orbitals. We calculate electron-phonon coupling strengths and transport properties in Al and, for the first time, in Nb and Mo. Our results are consistent with the experimental results and are compared with previous theoretical results.
