SCDFT, review and applications — •Antonio Sanna¹, Jose Flores-Livas², Arkady Daviydov¹, Andy Linscheid³, and E.K.U.

We review the theoretical framework of Density Functional Theory for SuperConductors (SCDFT) and present recent applications and extensions as the calculation of the superconducting order parameter in real space[1]. SCDFT unlike conventional McMillan-Eliashberg theory, leads to reliable critical temperatures in a completely parameter free fashion. We discuss a formal connection between these approaches, the relative advantages and disadvantages, and how Eliashberg theory is used as ground for functional construction and to help extracting all the relevant physical properties from the solution of the SCDFT Kohn-Sham equations.
