โฆ Synopsis
Based on the theory of strong coupling superconductors, we have derived a Tc equation. This equation is more accurate than, and seems to lack the disadvantages of, other Tc equations, and has features similar to the exact solution.

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
The thermodynamics of several elemental superconductors is computed from isotropic Eliashberg theory formulated on the imaginary frequency axis. A symmary of the available experimental literature is presented and a comparison with theory is given. The small disagreements that are found are all in th
