In this talk, I will discuss the algorithm and numerical techniques behind the periodic random-phase approximation (RPA) and GW implementations within the FHI-aims code, based on a numeric atom-centered orbital framework. Numerical accuracies and efficiencies that can be achieved with such an implementations will be demonstrate. Furthermore, I will briefly discuss some of our most recent attempts to correct the deficiencies of RPA and GW.
