When density correction is applied to this system, the energetics for the PBE optimization pathway are shifted upwards by about 0.1 Ha, placing DC-PBE in reasonable agreement with MP2. The same is true for DC-PBE along the PBE0 optimization pathway, only in that case the DC-PBE energy profile is free of the jumps that come from hopping of the localized HF spin density between Ti sites. At least in this system, DC-PBE appears to offer an alternative means to achieve MP2-quality results at HF cost. PBE0 already affords accurate energetics comparable to MP2 along the PBE, PBE0, and HSE06 optimization trajectories, but DC-PBE0 up-shifts these energetics by 0.02-0.03 Ha. The use of DC-PBE0 therefore does not offer any advantage over PBE0 itself, as both methods require the computational equivalent of a HF calculation.
