Emulator-assisted nuclear density-functional-theory inference and its consequences for the structure of neutron stars

Anonymous, Marco Antonelli, G. Colò, F. Gulminelli et autres

Nuclear density functional theory provides a unified description of finite nuclei and bulk nuclear matter, and is widely used to model the neutron star (NS) equation of state. However, extrapolations to suprasaturation densities require a quantified treatment of uncertainties arising from parameter …

Microscopic mechanism of the Fayans pairing for the enhancement of charge radii

Tomoya Naito, Gianluca Colò, X. Roca-Maza, Hiroyuki Sagawa et autres

The Fayans energy density functional (EDF), and in particular its pairing sector, have been claimed to be able to reproduce the experimental data of charge radii in many instances. A particularly intriguing case is that of the $ \mathrm{Ca} $ isotopes between …

The parity-violating asymmetry including QED corrections in high-energy electron-nucleus collisions

X. Roca-Maza, D. H. Jakubassa-Amundsen

Abstract The parity-violating asymmetry, accounting for the vector and axial-vector vertex plus self-energy correction as well as for vacuum polarization, is calculated nonperturbatively by solving the corresponding Dirac equation for the electronic scattering states. Investigating the nuclei 27 Al, 48 Ca and …

Radiative corrections to the parity-violating spin asymmetry

D. H. Jakubassa-Amundsen, X. Roca-Maza

The parity-violating spin asymmetry A pv for elastic electron scattering from spin-zero nuclei, together with its QED corrections, is evaluated nonperturbatively within the phase-shift analysis. Dispersion corrections, taking into account low-lying transient nuclear excitations, are estimated with the help of the lowest-order …

Synthesis of superheavy elements in the outer crust of a magnetar

D. Basilico, G. Colò, X. Roca-Maza

A theoretical understanding of a possible mechanism for synthesizing superheavy elements in the outer crust of magnetars is presented. We demonstrate that such a mechanism can be present whenever the baryon density in the outer crust of a neutron star reaches values …
