Light nuclei from chiral EFT interactions
P. Navratil, V. G. Gueorguiev, J. P. Vary +3
Recent developments in nuclear theory allow us to make a connection between quantum chromodynamics (QCD) and low-energy nuclear physics. First, chiral effective field theory (chiEF…
Convergence in the no-core shell model with low-momentum two-nucleon interactions
S. K. Bogner, R. J. Furnstahl, P. Maris +3
The convergence of no-core shell model (NCSM) calculations using renormalization group evolved low-momentum two-nucleon interactions is studied for light nuclei up to Li-7. Because…
Evidence for Symplectic Symmetry in Ab Initio No-Core Shell Model Results for Light Nuclei
Tomas Dytrych, Kristina D. Sviratcheva, Chairul Bahri +2
Clear evidence for symplectic symmetry in low-lying states of C and O is reported. Eigenstates of C and O, determined within the framework of the no-cor…
Global Properties of fp-Shell Interactions in Many-nucleon Systems
K. D. Sviratcheva, J. P. Draayer, J. P. Vary
Spectral distribution theory, which can be used to compare microscopic interactions over a broad range of nuclei, is applied in an analysis of two modern effective interactions bas…
Underlying symmetries of realistic interactions and the nuclear many-body problem
K. D. Sviratcheva, J. P. Draayer, J. P. Vary
The present study brings forward important information, within the framework of spectral distribution theory, about the types of forces that dominate three realistic interactions,…
Dynamical Symmetries Reflected in Realistic Interactions
K. D. Sviratcheva, J. P. Draayer, J. P. Vary
Realistic nucleon-nucleon (NN) interactions, derived within the framework of meson theory or more recently in terms of chiral effective field theory, yield new possibilities for ac…
