LDA outperforms other functionals for monovacancy formation energies in fcc metals, while the LAK meta-GGA yields the highest accuracy for interstitials in diamond silicon, approaching QMC benchmarks.
rt-TDDFT simulations show ultrafast laser excitation induces C3v symmetry breaking in NV- centers via minority-spin electron promotion, dynamic Jahn-Teller distortions, and propagating coherent phonons at ~2 Å/fs.
