Coupled cluster calculations of ground and excited states of nuclei
K. Kowalski, D. J. Dean, M. Hjorth-Jensen +2
The standard and renormalized coupled cluster methods with singles, doubles, and noniterative triples and their generalizations to excited states, based on the equation of motion c…
Pairing correlations and transitions in nuclear systems
A. Belic, D. J. Dean, M. Hjorth-Jensen
We discuss several pairing-related phenomena in nuclear systems, ranging from superfluidity in neutron stars to the gradual breaking of pairs in finite nuclei. We describe recent e…
Coupled cluster approach to nuclear physics
D. J. Dean, M. Hjorth-Jensen
Using many-body perturbation theory and coupled-cluster theory, we calculate the ground-state energy of He-4 and O-16. We perform these calculations using a no-core G-matrix intera…
Solution of large scale nuclear structure problems by wave function factorization
T. Papenbrock, A. Juodagalvis, D. J. Dean
Low-lying shell model states may be approximated accurately by a sum over products of proton and neutron states. The optimal factors are determined by a variational principle and r…
Systematic study of deformed nuclei at the drip lines and beyond
M. V. Stoitsov, J. Dobaczewski, W. Nazarewicz +2
An improved prescription for choosing a transformed harmonic oscillator (THO) basis for use in configuration-space Hartree-Fock-Bogoliubov (HFB) calculations is presented. The new…
Factorization of shell-model ground-states
T. Papenbrock, D. J. Dean
We present a new method that accurately approximates the shell-model ground-state by products of suitable states. The optimal factors are determined by a variational principle and…
