The possibility of using temperature-dependent angle-resolved-photoemission data to derive an effective {alpha}{sup 2}{ital F} for high-temperature superconductors via a Nambu-Eliashberg inversion is investigated. On analyzing data of Dessau {ital et

We have simulated the atomic structure of Ni-P amorphous alloys for several concentrations (${\mathrm{Ni}}_{75}$${\mathrm{P}}_{25}$, ${\mathrm{Ni}}_{80}$${\mathrm{P}}_{20}$, and ${\mathrm{Ni}}_{85}$${\mathrm{P}}_{15}$), and have calculated their elec

We have considered boson exchange models of high-temperature superconductors which use Eliashberg theory and in which the bare bosons have sharp spectral features. In particular, we have calculated the boson linewidth due to the interaction with the

We have modeled the Ni-P amorphous alloy system by a set of supercells on which we have carried out calculations of electronic and transport properties. The thermopower is determined by calculating the energy dependence of the dc electrical conductiv

The temperature-dependent angle-resolved photoemission data of D.S. Dessau et al 1 on Bi 2212 show strong modulations in the superconducting state when compared to the normal state. These are similar to those seen historically in standard tunneling e

In order to study the magnitude of the vertex correction in the infrared absorption in a superconductor, we have calculated the and ω dependent response function for a simple Debye model of a superconductor. We have carried out our calculations for

The results of calculations for a number of electron-phonon interaction effects for tantalum are presented. The calculations are based on Korringa-Kohn-Rostoker energy bands, Born--von K\'arm\'an phonons, and the rigid-muffin-tin approximation for th

The anisotropic mass enhancement and anisotropic superconducting energy gap are calculated for zinc using pseudopotential theory. The phonon frequencies and polarization vectors are obtained from a model developed here which uses Shaw's optimized mod
