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…
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)->…
New Procedure for Evaluation of U(3) Coupling and Recoupling Coefficients
Phong Dang, Jerry P. Draayer, Feng Pan +1
A simple method to calculate Wigner coupling coefficients and Racah recoupling coefficients for U(3) in two group-subgroup chains is presented. While the canonical U(3)->U(2)->U(1)…
Uncertainty Quantification of Collective Nuclear Observables From the Chiral Potential Parametrization
Kevin S. Becker, Kristina D. Launey, Andreas Ekström +4
We perform an uncertainty estimate of quadrupole moments and B(E2) transition rates that inform nuclear collectivity. In particular, we study the low-lying states of 6Li and 12C us…
Understanding the Effect of Chiral NN Parametrization on Nuclear Shapes From an Ab Initio Perspective
Kevin S. Becker, Kristina D. Launey, Andreas Ekström +5
The ab initio symmetry-adapted no-core shell model naturally describes nuclear deformation and collectivity, and is therefore well-suited to studying the dynamics and coexistence o…
Ab Initio Symmetry-Adapted Emulator for Studying Emergent Collectivity and Clustering in Nuclei
Kevin S. Becker, Kristina D. Launey, Andreas Ekström +1
We discuss emulators from the ab initio symmetry-adapted no-core shell-model framework for studying the formation of alpha clustering and collective properties without effective ch…
