Description

Updates the Dirac-Fock code to correctly read in orbitals from moldft to compute a closed-shell system. PR is purposely more minimal to keep implementation independent of MPQC.

Note, I did have working version of DFdriver using small memory exchange algorithm, but it was 10x slower than current algo due to need for better calls to vmra.h and mra.h. Seems better to leave exchange as is to have independent implementation from MPQC, which does use smallmem exchange algorithm for bispinors.

Details

  • Adds point charge nucleus model, option is nucleus == 2
  • Properly computes closed-shell computation, without Kramers symmetry
  • Converge either due to BSH residuals or energy, density, and BSH residuals
  • Updates for speed of light and bohr radius in fm to CODATA 2022 values
