Emulation of Proton-Deuteron Scattering via the Reduced Basis Method and Active Learning: Detailed Description
Alex Gnech, Xilin Zhang, Christian Drischler +5
Nucleon-deuteron () scattering can be used to constrain three-nucleon forces in chiral effective field theory (EFT). However, high-fidelity calculations, such as the Hypers…

Accurate and Efficient Emulation of Proton-Deuteron Scattering via the Reduced Basis Method and Active Learning
Alex Gnech, Xilin Zhang, Christian Drischler +5
We introduce highly accurate and efficient emulators for proton-deuteron scattering below the deuteron breakup threshold. We explore two different reduced-basis method strategies:…

The excited state of the -particle: a benchmark study
Pierre-Yves Duerinck, Arnoldas Deltuva, Jérémy Dohet-Eraly +5
A benchmark study is performed for the excited state of He. When the Coulomb interaction is switched off, the He nucleus exhibits a bound excited state in the vicinity of $…
