Unphysical Solutions in Coupled-Cluster-Based Random Phase Approximation and How to Avoid Them
Ruiheng Song, Xiliang Gong, Hong-Zhou Ye
The direct ring coupled-cluster doubles (drCCD)-based random phase approximation (RPA) has provided an attractive framework for the development and application of RPA-related metho…
