Four-neutron halo model at the unitary limit
R. M Francisco, D. S. Rosa, G. Hupin +2
In some neutron-rich nuclei usually treated as two-neutron halos, the core can itself be resolved into a subcore-neutron-neutron subsystem, so that four valence neutrons may be inv…
Momentum Distribution and Contact Parameters of a mass-imbalanced three-body system across the Efimov-Unatomic transition
D. S. Rosa, R. M. Francisco, T. Frederico +2
The paper analyzes how the single‑particle momentum distribution and contact parameters behave in mass‑imbalanced three‑body systems at the critical dimension where discrete Efimov…
Geometric structure of two-neutron halo nuclei from Efimov physics at the unitary limit
R. M. Francisco, D. S. Rosa, T. Frederico +1
We investigate the geometric structure of two-neutron halo nuclei from the perspective of Efimov physics. Using the analytic three-body wave function obtained from the Faddeev equa…
Confinement-induced unatomic trimer states in mass-imbalanced systems
Rafael M. Francisco, D. S. Rosa, T. Frederico +2
As resonantly interacting trimers of the type AAB are progressively squeezed from to , unatomic states emerge. We calculated the contacts from the high momentum tail of…
