Bayesian analysis of muon capture on deuteron in chiral effective field theory
Alex Gnech, Laura Elisa Marcucci, Michele Viviani
We compute the muon capture on deuteron in the doublet hyperfine state for a variety of nuclear interactions and consistent nuclear currents. Our analysis includes a detailed exami…
Theoretical calculation of the radiative capture reaction
Alex Gnech, Laura Elisa Marcucci
We present a new calculation of the radiative capture astrophysical -factor in a cluster model framework. We consider several intercluster poten…
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:…
Solving the homogeneous Bethe-Salpeter equation with a quantum annealer
Filippo Fornetti, Alex Gnech, Tobias Frederico +6
The homogeneous Bethe-Salpeter equation (hBSE), describing a bound system in a genuinely relativistic quantum-field theory framework, was solved for the first time by using a D-Wav…
Calculation of the Li ground state within the hyperspherical harmonic basis
Alex Gnech, Michele Viviani, Laura Elisa Marcucci
We have studied the solution of the six-nucleon bound state problem using the hyperspherical harmonic (HH) approach. For this study we have considered only two-body nuclear forces.…
Quantum Monte Carlo calculations of Zemach moments in nuclei
Garrett B. King, Sonia Bacca, Graham Chambers-Wall +4
Modern atomic spectroscopy has reached a level of precision at which nuclear-structure effects can no longer be neglected and must be quantified reliably. In particular, hyperfine…
