Density functional theory (the use of only the density to calculate energies) is known to fail first adapting the code in a book from C++ into Python.

Density-functional theory (DFT) is a ubiquitous theoretical framework for finding approximate solutions to quantum mechanics; calculations using a modern DFT package are sufficiently robust and accurate that insight
KH Computational Physics- 2015 Density Functional Theory (DFT) recursion relation xi+1 ?2xi +xi?1 =h 2(f ixi +ui) (5) But we know from the differential equation that x(4) = d2x??(t) dt2 = d2 dt2 (f(t)x(t)+u(t)) (6) which can be approximated by x(4) ? fi+1xi+1 +ui+1?2fixi ?2ui +fi?1xi?1 +ui?1 h2 (7)
The program is based on the Green’s function method with the local rigid spin rotation treated as a perturbation As input the package uses the output of either Wannier90 which is interfaced with many density functional theory packages or of codes based on localised orbitals
of developing implementing and benchmarking charge corrections for density functional theory (DFT) point defect calculations is still an open challenge To contribute to this goal a parallelized Python and C package called pawpyseed is developed to perform numerical analysis of DFT wavefunctions in the projector augmented wave (PAW) formalism
