Computational Nuclear Quantum Many-Body Problem: The UNEDF Project
Scott Bogner, Aurel Bulgac, Joseph A. Carlson +28
The UNEDF project was a large-scale collaborative effort that applied high-performance computing to the nuclear quantum many-body problem. UNEDF demonstrated that close association…
Time-dependent coupled-cluster method for atomic nuclei
D. A. Pigg, G. Hagen, H. Nam +1
We study time-dependent coupled-cluster theory in the framework of nuclear physics. Based on Kvaal's bi-variational formulation of this method [S. Kvaal, arXiv:1201.5548], we expli…
UNEDF: Advanced Scientific Computing Collaboration Transforms the Low-Energy Nuclear Many-Body Problem
H. Nam, M. Stoitsov, W. Nazarewicz +10
The demands of cutting-edge science are driving the need for larger and faster computing resources. With the rapidly growing scale of computing systems and the prospect of technolo…
Origin of the anomalous long lifetime of 14C
P. Maris, J. P. Vary, P. Navratil +3
We report the microscopic origins of the anomalously suppressed beta decay of 14C to 14N using the ab initio no-core shell model (NCSM) with the Hamiltonian from chiral effective f…
Pairing Reentrance Phenomenon in Heated Rotating Nuclei in the Shell Model Monte Carlo Approach
D. J. Dean, K. Langanke, H. A. Nam +1
Rotational motion of heated 72-Ge is studied within the microscopic Shell Model Monte Carlo approach. We investigate the the angular momentum alignment and nuclear pairing correlat…
A new puzzle for random interaction
Calvin W. Johnson, Hai Ah Nam
We continue a series of numerical experiments on many-body systems with random two-body interactions, by examining correlations in ratios in excitation energies of yrast = 0, 2…
