The convergence of RPA total energies is dependent on DFT total energies, DFT wavefunctions, the exact exchange, and RPA correlation energies. The convergence of DFT calculations is well-understood, and many works discussing relevant parameters have been published. Calculations quantifying how RPA total energies converge with respect to a variety of interrelated computational parameters have been previously published, which are notably based on DFT results using PAW pseudopotentials. In this work, we performed similar benchmarking for DFT results calculated using the SG15 ONCV pseudopotential set and the implementation of the above approach in BerkeleyGW. A full summary of the computational details used to perform these calculations is provided in the Computational Details section. In this section, we highlight how broadening, k/q-grid, and the static subpsace approximation impact RPA total energies because they are most directly tied to the new implementation described above. We also demonstrate the application of our approach to catalysts relevant to (electro)catalysis.
