Archivio Istituzionale della RicercaWe discuss the effects of quasiparticle energy dependence of the normal density of states on the Eliashberg equations in the case of high-Tc superconductors and compare the numerical results with our recent tunneling experimental data in Bi2Sr2CaCu2O8+x with Tc = 93 K. We also consider the possibility of quasiparticle energy dependence of the electron-phonon spectral function α2(Ω)F(Ω) and calculate its effects on the superconducting density of states.

Abstract
We discuss the effects of quasiparticle energy dependence of the normal density of states on the Eliashberg equations in the case of high-Tc superconductors and compare the numerical results with our recent tunneling experimental data in Bi2Sr2CaCu2O8+x with Tc = 93 K. We also consider the possibility of quasiparticle energy dependence of the electron-phonon spectral function α2(Ω)F(Ω) and calculate its effects on the superconducting density of states.
