Overall, the RT-TDHF propagation of the electron density for the largest of the three molecules shows the smallest errors from the expected behavior. However, the errors are still significant for a system with 68 electrons, and it is unclear if the errors will continue to decrease with increasing system size. Although the larger system shows more significant state mixing as seen in the large dipole oscillations and large population of the virtual orbital space, it may be that for charge transfer and resonantly driven electron dynamics that there is indeed smaller errors in real-time electron dynamics for large molecular and materials systems. This finding provides key insight and guidance when performing simulations of the electron transfer pathways in molecules and materials.
