Coupled-cluster theory for three-body Hamiltonians
G. Hagen, T. Papenbrock, D. J. Dean +4
We derive coupled-cluster equations for three-body Hamiltonians. The equations for the one- and two-body cluster amplitudes are presented in a factorized form that leads to an effi…
Coupled-cluster calculations for valence systems around O-16
J. R. Gour, P. Piecuch, M. Hjorth-Jensen +2
We study the ground and low-lying excited states of O-15, O-17, N-15, and F-17 using modern two-body nucleon-nucleon interactions and the suitably designed variants of the ab initi…
Ab initio coupled-cluster study of 16-O
M. Wloch, D. J. Dean, J. R. Gour +4
We report converged results for the ground and excited states and matter density of 16-O using realistic two-body nucleon-nucleon interactions and coupled-cluster methods and forma…
Nuclear Structure Calculations with Coupled Cluster Methods from Quantum Chemistry
D. J. Dean J. R. Gour, G. Hagen, M. Hjorth-Jensen +4
We present several coupled-cluster calculations of ground and excited states of 4He and 16O employing methods from quantum chemistry. A comparison of coupled cluster results with t…
