TL;DR: In this paper, an approach to the description of superconductors in thermal equilibrium is developed within a formally exact density functional framework, formulated in terms of three "densities": the ordinary electron density, the superconducting order parameter, and the diagonal of the nuclear N-body density matrix.

TL;DR: In this paper, the density functional theory for superconductors is applied to the calculation of superconducting properties of several elemental metals and the results for the transition temperature, for the gap at zero temperature, and for thermodynamic properties like the specific heat are obtained.

TL;DR: It is demonstrated that in this simple system, a very high superconducting critical temperature can be reached via electron-phonon and Coulomb electron-electron interactions.

TL;DR: The results show an unprecedented agreement with experiments, assess the predictive power of the method over a wide range of densities and electron-phonon couplings, and provide predictions for K, where no experiments exist so far.

TL;DR: In this paper, the role of gap anisotropy over the Fermi surface (multi-gap superconductivity) was investigated using density functional theory for superconductors.
