Extrapolation to infinite model space of no-core shell model calculations using machine learning
Aleksandr Mazur, Roman Sharypov, Andrey Shirokov
An ensemble of neural networks is employed to extrapolate no-core shell model (NCSM) results to infinite model space for light nuclei. We present a review of our neural network ext…
Machine Learning for Extrapolating No-Core Shell Model Results to Infinite Basis
R. E. Sharypov, A. I. Mazur, A. M. Shirokov
We utilize the machine learning to extrapolate to the infinite model space the no-core shell model (NCSM) results for the energies and rms radii of the 6He ground state and 6Li low…
Tetraneutron resonance and its isospin analogues
A. M. Shirokov, A. I. Mazur, I. A. Mazur +1
We discuss isospin analogues of the tetraneutron resonance and their possible manifestations in nuclear structure and reactions.
Trineutron resonances in the SS-HORSE-NCSM approach
I. A. Mazur, M. K. Efimenko, A. I. Mazur +4
The SS-HORSE-NCSM method is generalized to the case of democratic decay into an odd number of fragments. This method is applied to the search for resonances in three-neutron system…
SS-HORSE Extension of the No-Core Shell Model: Application to Resonances in
I. A. Mazur, I. J. Shin, Y. Kim +4
Theoretical ab initio studies of resonances in the unbound nucleus are presented. We perform no-core shell model calculations with interactions Daejeon16 and JIS…
Improved description of light nuclei through chiral effective field theory at leading order
M. Sanchez Sanchez, N. A. Smirnova, A. M. Shirokov +2
We propose an arrangement of the most commonly invoked version of the two-nucleon chiral potential such that the low-lying amplitude zero of the 1S0 partial wave is captured at lea…
