Spectral distribution functions of electron-phonon interaction α 2 F (ω) obtained by ab initio linear-response calculations are used to describe various superconducting and transport properties in a number of elemental metals such as Al, Cu, M o, N b, P b, P d, T a, and V. Their lattice dynamics and self-consistently screened electron-phonon coupling are evaluated within local density functional theory and using linear-muffin-tin-orbital basis set. We compare our theoretical α 2 F (ω) with those deduced from the tunneling measurements and find a close agreement between them. Temperature dependent electrical and thermal resistivities as well as transport constants λtr also agree well with the experimental data. The values of λtr are close to the electron-phonon coupling parameter λ. For the later a very good agrement with specific-heat measurements was found without any paramagnon contribution, except in P d. We conclude that our method provides the description of electron-phonon interactions in tested materials with the accuracy 10%.

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 mufBn-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.
