Ab initio calculations of nuclear charge radii across and beyond Sn: Putting chiral EFT nuclear interactions to the test
Pepijn Demol, Urban Vernik, Thomas Duguet +1
Charge radii are investigated along the Tin isotopic chain via ab initio Bogoliubov coupled cluster calculations at the singles and doubles level. In addition to the reproduction o…
Exploring quark mass dependent three-nucleon forces in medium-mass nuclei
Urban Vernik, Kai Hebeler, Achim Schwenk
Recently, new quark mass dependent three-nucleon (3N) forces have been identified, whose contributions in nuclear matter exceed expectations of Weinberg power-counting arguments. I…
Neutron star crust and outer core equation of state from chiral effective field theory with quantified uncertainties

We study the order-by-order expansion of the energy per particle of asymmetric nuclear matter up to twice saturation density in chiral effective field theory (EFT) within a Bayesia…
From closed shells to open shells: Coupled-cluster calculations of atomic nuclei
F. Marino, F. Bonaiti, P. Demol +6
Coupled-cluster theory is a powerful tool for first-principles calculations of atomic nuclei, enabling accurate predictions of nuclear observables across the Segrè chart. While cou…
Ab initio calculations of monopole sum rules: From finite nuclei to infinite nuclear matter
Francesca Bonaiti, Andrea Porro, Sonia Bacca +2
We compute moments of the isoscalar monopole response of N = Z closed-shell nuclei based on chiral nucleon-nucleon plus three-nucleon interactions. We employ the random phase appro…

We report on the first quantum Monte Carlo calculations of helium isotopes with fully propagated theoretical uncertainties from the interaction to the many-body observables. To ach…
Hartree-Fock emulators for nuclei: Application to charge radii of Ca
Margarida Companys Franzke, Alexander Tichai, Kai Hebeler +1
Understanding the emergence of complex structures of nuclei from chiral effective field theory (EFT) is a central challenge. The large number of low-energy couplings (LECs) in the…
Ab initio calculations of beta-decay half-lives for neutron-rich nuclei
Zhen Li, Takayuki Miyagi, Achim Schwenk
Beta-decay rates of extreme neutron-rich nuclei remain largely unknown experimentally, while they are critical inputs for -process nucleosynthesis. We present first ab initio ca…
Ab initio computations of the fourth-order charge density moments of Ca and Pb
T. Miyagi, M. Heinz, A. Schwenk
Neutron skins of neutron-rich nuclei connect nuclei with the matter in neutron stars. High-precision measurements of nuclear charge densities to extract higher-order moments are pr…

Yingjie Zhou, Susanne Glässel, Yue-Hang Leung +12
The study of the nuclear equation-of-state (EoS) is a one of the primary goals of experimental and theoretical heavy-ion physics. The comparison of recent high statistics data from…
Bayesian approach for many-body uncertainties in nuclear structure: Many-body perturbation theory for finite nuclei
Isak Svensson, Alexander Tichai, Kai Hebeler +1
A comprehensive assessment of theoretical uncertainties defines an important frontier in nuclear structure research. Ideally, theory predictions include uncertainty estimates that…
