WebThe density functional theory (DFT) has been utilized to describe the electron interaction in superconducting materials. This paper discusses the fundamental aspects to begin with the DFT, including local density approximation (LDA) as well as its necessary transformation into time dependent system (TDDFT) and superconducting state (SCDFT).
