Within the framework of the Eliashberg theory including the energy-dependent Lorentzian electronic density of states (EDOS), the behavior of the quasiparticle density of states (QDOS) is studied for strong-coupling superconductors. Our numerical calculation shows that when the EDOS has structure it
We have calculated the specific heat difference between normal and superconducting state at all temperatures (T) below Tc as a function of coupling strength spanning weak, intermediate and very strong coupling. We establish a maximum for the slope at Tc as well as for its value normalized to the jum
