Accurate effective potential for density amplitude and the corresponding Kohn-Sham exchange-correlation potential calculated from approximate wavefunctions
Ashish Kumar, Rabeet Singh, Manoj K. Harbola
Over the past few years it has been pointed out that direct inversion of accurate but approximate ground state densities leads to Kohn-Sham exchange-correlation (xc) potentials tha…

Universal nature of different methods of obtaining the exact Kohn-Sham exchange-correlation potential for a given density
Ashish Kumar, Rabeet Singh, Manoj K. Harbola
An interesting fundamental problem in density-functional theory of electronic structure of matter is to construct the exact Kohn-Sham (KS) potential for a given density. The exact…

A study of accurate exchange-correlation functionals through adiabatic connection
Rabeet Singh, Manoj K. Harbola
A systematic way of improving exchange-correlation energy functionals of density functional theory has been to make them satisfy more and more exact relations. Starting from the in…
