Bridging Ab Initio Symmetries and Global Nuclear Masses with Interpretable Neural Networks
Phong Dang, Evander Espinoza, Xiaoliang Wan +6
Ab initio theory establishes Wigner's SU(4) and Elliott's SU(3) as dominant symmetries of the nuclear force in light and intermediate-mass nuclei. Previous work shows the relevance…
Ab initio calculation of symmetry-breaking observables
A Belley, B. Romeo, J. Engel +8
Symmetry-violating observables such as the nuclear anapole and Schiff moments provide sensitive probes of the fundamental symmetries of nature and physics beyond the Standard Model…
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 la…
Coupling and Recoupling Coefficients for Wigner's U(4) Supermultiplet Symmetry
Phong Dang, Jerry P. Draayer, Feng Pan +5
A novel procedure for evaluating Wigner coupling coefficients and Racah recoupling coefficients for U(4) in two group-subgroup chains is presented. The canonical U(4)->U(3)->U(2)->…
Exact isovector pairing in a shell-model framework: Role of proton-neutron correlations in isobaric analog states
M. E. Miora, K. D. Launey, D. Kekejian +2
We utilize a nuclear shell model Hamiltonian with only two adjustable parameters to generate, for the first time, exact solutions for pairing correlations for light to medium-mass…
