Reduced scaling implementation of the coupled cluster-based static embedding method, MPCC with density fitting

Avijit Shee, Fabian M. Faulstich, K. Birgitta Whaley +2

An improved algorithm to implement our previously proposed static quantum embedding method MPCC (J. Chem. Phys. 161, 164107 (2024)) is presented. It uses the density-fitting (DF) a…

Consistent inclusion of triple substitutions within a coupled cluster based static quantum embedding theory

Avijit Shee, Fabian M. Faulstich, K. Birgitta Whaley +2

We incorporate a solver for the fragment problem with accuracy beyond coupled cluster singles and doubles (CCSD) into the previously proposed static embedding framework, MPCC. To t…

Real-time propagation of adaptive sampling selected configuration interaction wave function

Avijit Shee, Zhen Huang, Martin Head-Gordon +1

We have developed a new time propagation method, time-dependent adaptive sampling configuration interaction (TD-ASCI), to describe the dynamics of a strongly correlated system. We…

A static quantum embedding scheme based on coupled cluster theory

Avijit Shee, Fabian M. Faulstich, Birgitta Whaley +2

We develop a static quantum embedding scheme that utilizes different levels of approximations to coupled cluster (CC) theory for an active fragment region and its environment. To r…

Comparing self-consistent GW and vertex corrected G0W0 (G0W0Γ) accuracy for molecular ionization potentials

Ming Wen, Vibin Abraham, Gaurav Harsha +3

We test the performance of self-consistent GW and several representative implementations of vertex corrected G0W0 (G0W0Γ). These approaches are tested on benchmark data sets coveri…
