QM is the correct mathematical description of the behavior of electrons and thus of chemistry. WebThe focus on ab initio DFT does not mean we propose abandoning the successes of the empirical EDF’s, which already achieve an accuracy for known nuclear masses that will be hard to reach directly with ab initio functionals. Furthermore, it will only be possible in the near future to make ab initio calculations of a limited subset of all nuclei. nothics eye
