Possible inconsistency between phenomenological and theoretical determinations of charge symmetry breaking in nuclear energy density functionals
Tomoya Naito, Gianluca Colò, Tetsuo Hatsuda +3
We summarize the recent progress on the determination of the charge symmetry breaking term of nuclear energy density functionals. We point out that the strength of the term determi…
Neural Polytopes
Koji Hashimoto, Tomoya Naito, Hisashi Naito
We find that simple neural networks with ReLU activation generate polytopes as an approximation of a unit sphere in various dimensions. The species of polytopes are regulated by th…
Revisiting the extraction of charge radii of Ca and Pb with muonic atom spectroscopy
Hui Hui Xie, Tomoya Naito, Jian Li +1
The extractions of nuclear charge radii from muonic atom spectroscopy for Ca and Pb are revisited to analyze the model dependencies induced by employing a Fermi-type…
QCD-based charge symmetry breaking interaction and the Okamoto-Nolen-Schiffer anomaly
Hiroyuki Sagawa, Tomoya Naito, Xavier Roca-Maza +1
An approach is proposed to link the charge symmetry breaking (CSB) nuclear interaction and the low-energy constants in quantum chromodynamics (QCD) by matching the CSB effect in nu…
Empirical neutron star mass formula based on experimental observables
Hajime Sotani, Tomoya Naito
We derive the empirical formulae expressing the mass and gravitational redshift of a neutron star, whose central density is less than threefold the nuclear saturation density, as a…
Multi-body wave function of ground and low-lying excited states using unornamented deep neural networks
Tomoya Naito, Hisashi Naito, Koji Hashimoto
We propose a method to calculate wave functions and energies not only of the ground state but also of low-lying excited states using a deep neural network and the unsupervised mach…
Effects of Coulomb and isospin symmetry breaking interactions on neutron-skin thickness
Tomoya Naito, Gianluca Colò, Haozhao Liang +2
Both the Coulomb interaction and isospin symmetry breaking (ISB) parts of the nuclear interaction break the isospin symmetry in atomic nuclei. Effects of these two kinds of interac…
