Approximate Green's Function Coupled Cluster Method Employing Effective Dimension Reduction

Bo Peng, Roel Van Beeumen, David B. Williams-Young +2

The Green's function coupled cluster (GFCC) method is a powerful many-body tool for computing the electronic structure of molecular and periodic systems, especially when electrons…

Downfolding of many-body Hamiltonians using active-space models: extension of the sub-system embedding sub-algebras approach to unitary coupled cluster formalisms

Nicholas P. Bauman, Eric J. Bylaska, Sriram Krishnamoorthy +3

In this paper we outline the extension of recently introduced the sub-system embedding sub-algebras coupled cluster (SES-CC) formalism to the unitary CC formalism. In analogy to th…
