Random Phase Approximation Correlation Energy using Real-Space Density Functional Perturbation Theory
Boqin Zhang, Shikhar Shah, John E. Pask +2
We present a real-space method for computing the random phase approximation (RPA) correlation energy within Kohn-Sham density functional theory, leveraging the low-rank nature of t…
