The normal state of attractive Fermi gases from coupled-cluster theory
James M. Callahan, John Sous, Timothy C. Berkelbach
We introduce coupled-cluster (CC) theory for the numerical study of the normal state of two-component, dilute Fermi gases with attractive, short-range interactions at zero temperat…

Dynamical correlation energy of metals in large basis sets from downfolding and composite approaches
James M. Callahan, Malte F. Lange, Timothy C. Berkelbach
Coupled-cluster theory with single and double excitations (CCSD) is a promising ab initio method for the electronic structure of three-dimensional metals, for which second-order pe…
