Neutron matter from local chiral effective field theory interactions at large cutoffs
I. Tews, R. Somasundaram, D. Lonardoni +6
Neutron matter is an important many-body system that provides valuable constraints for the equation of state (EOS) of neutron stars. Neutron-matter calculations employing chiral ef…

Impact of two-body currents on magnetic dipole moments of nuclei
T. Miyagi, X. Cao, R. Seutin +5
We investigate the effects of two-body currents on magnetic dipole moments of medium-mass and heavy nuclei using the valence-space in-medium similarity renormalization group with c…

Magnetic dipole operator from chiral effective field theory for many-body expansion methods
R. Seutin, O. J. Hernandez, T. Miyagi +4
Many-body approaches for atomic nuclei generally rely on a basis expansion of the nuclear states, interactions, and current operators. In this work, we derive the representation of…
