We construct nucleonic microscopic optical potentials by combining the Green’s function approach with the coupled-cluster method for \(^{40}\mathrm {Ca}\) and \(^{48}\mathrm {Ca}\). We work with the chiral nucleon-nucleon and three-nucleon interact

Microscopic optical potentials for calcium isotopes

Autor: Pawel Danielewicz, Jimmy Rotureau, Gustav R. Jansen, Gaute Hagen, Filomena Nunes

We construct nucleonic microscopic optical potentials by combining the Green's function approach with the coupled-cluster method for $\rm{^{40}Ca}$ and $\rm{^{48}Ca}$. For the computation of the ground-state of $\rm{^{40}Ca}$ and $\rm{^{48}Ca}$, we u

Energy Spectrum of Neutron-Rich Helium Isotopes: Complex Made Simple

Autor: Witold Nazarewicz, K. Fossez, Jimmy Rotureau

We demonstrate that the intricate energy spectrum of neutron-rich helium isotopes can be straightforwardly described by taking advantage of the low-energy properties of neutron-neutron interaction and the scale separation that is present in diluted d
