The role of the reference state in long-range random phase approximation correlation

Benjamin G. Janesko and Gustavo E. Scuseria We recently presented a combination of a short-range density functional approximation with long-range random phase approximation (RPA) correlation [B. G. Janesko, T. M. Henderson, and G. E. Scuseria, J. Chem. Phys. 130, 081105 (2009)]. Here we explore how this approximation's performance is affected ... [J. Chem.
