Benchmarking ANN extrapolations of the ground-state energies and radii of Li isotopes
Marco Knöll, Matthew Lockner, Pieter Maris +4
We present a comparison of model-space extrapolation methods for No-Core Shell Model calculations of ground-state energies and root-mean-square radii in Li isotopes. In particular,…
Machine Learning for Correlations of Electromagnetic Properties in Ab Initio Calculations
Marco Knöll, Marc L. Agel, Tobias Wolfgruber +2
In ab initio nuclear structure theory, accurately predicting electromagnetic observables, such as moments and transition rates, is essential for a comprehensive understanding of nu…
Halo Structures in p-Shell Hypernuclei with Natural Orbitals
Marco Knöll, Robert Roth
We extend the concept of natural orbitals as an optimized single-particle basis for ab initio nuclear many-body calculations to hypernuclei and show that their superior properties,…
High-Precision Ab Initio Radius Calculations of Boron Isotopes
Tobias Wolfgruber, Tobias Gesser, Marco Knöll +2
We perform a precision study of radii in Boron isotopes for multiple realistic interactions from chiral effective field theory. We obtain predictions of radii with combined many-bo…
