FHI-aims can run the GW calculation in a single shot, without having to restart the calculation after completing an SCF cycle. Such a run will consist of an SCF part, during which the ground-state electronic density is obtained, and a post-SCF part when the GW self-energy is evaluated. However, the two parts can also be separated using FHI-aims restart capabilities. The GW workflow for FHI-aims, implemented in the atomate2 package, dumps the resulting SCF eigenfunctions and reads them at the beginning of the GW run. It helps in several ways by: 1) making calculations more computationally efficient, 2) achieving consistency in the results, and 3) allowing more flexible exploration of the parameters space.
