Bridging Ab Initio Symmetries and Global Nuclear Masses with Interpretable Neural Networks
Phong Dang, Evander Espinoza, Xiaoliang Wan +6
Ab initio modeling has established Wigner's SU(4) and Elliott's SU(3) as dominant symmetries of the nuclear force in light and intermediate-mass nuclei. We ask whether they also go…
Proton and Neutron Elastic Scattering on He Targets from SA-NCSM Optical Potentials
Darin C. Mumma, Matthew B. Burrows, Kristina D. Launey +2
We construct and discuss nucleon-nucleus optical potentials at low energies for He targets. In this work, we use the SA-NCSM/GF…
Unmasking Hidden Wigner's Symmetry from First Principles
Phong Dang, Daniel Langr, Tomas Dytrych +2
We present quantitative evidence that high-quality internucleon forces derived from EFT exhibit a striking dominance of Wigner's supermultiplet symmetry, without invoking the l…
Symplectic no-core configuration interaction framework for nuclear structure
Anna E. McCoy, Mark A. Caprio, Patrick J. Fasano +1
We present the symplectic no-core configuration interaction (SpNCCI) framework, in which the nuclear many-body problem is solved a symmetry-adapted basis that explicitly encodes ap…
Unexpected Rise in Nuclear Collectivity from Short-Range Physics
Kevin S. Becker, Kristina D. Launey, Andreas Ekström +4
We discover a surprising relation between the collective motion of nucleons within atomic nuclei, traditionally understood to be driven by long-range correlations, and short-range…
