Minimal nuclear energy density functional

A Bulgac, MMN Forbes, S Jin, RN Perez, N Schunck - Physical Review C, 2018 - APS
We present a minimal nuclear energy density functional (NEDF) called “SeaLL1” that has
the smallest number of possible phenomenological parameters to date. SeaLL1 is defined …

Nuclear masses set bounds on quantum chaos

J Barea, A Frank, JG Hirsch, PV Isacker - Physical review letters, 2005 - APS
It has been suggested that chaotic motion inside the nucleus may significantly limit the
accuracy with which nuclear masses can be calculated. Using a power spectrum analysis …

Learning correlations in nuclear masses using neural networks

A Sharma, A Gandhi, A Kumar - Physical Review C, 2022 - APS
There have been great improvements in the predictions of nuclear masses, yet it is difficult to
exactly reproduce the measured nuclear mass. It has been suggested that the cause of such …

Classical chaos in the geometric collective model

P Stránský, M Kurian, P Cejnar - Physical Review C—Nuclear Physics, 2006 - APS
Collective vibrations and rotations of atomic nuclei are investigated from the classical
viewpoint within the geometric collective model. It is shown that the model, even in its …

Bounds on the presence of quantum chaos in nuclear masses

JG Hirsch, A Frank, J Barea, P Van Isacker… - The European Physical …, 2005 - Springer
Differences between measured nuclear masses and those calculated using the Finite-
Range Droplet Model are analyzed. It is shown that they have a well defined, clearly …

Nuclear energy density functionals: What do we really know?

A Bulgac, MMN Forbes, S Jin - arXiv preprint arXiv:1506.09195, 2015 - arxiv.org
We present the simplest nuclear energy density functional (NEDF) to date, determined by
only 4 significant phenomenological parameters, yet capable of fitting measured nuclear …

The art of predicting nuclear masses

JG Hirsch, I Morales, J Mendoza-Temis… - … Journal of Modern …, 2008 - World Scientific
A review of recent advances in the theoretical analysis of nuclear mass models and their
predictive power is presented. After introducing two tests which probe the ability of nuclear …

Nuclear masses, chaos, and the residual interaction

A Molinari, HA Weidenmüller - Physics Letters B, 2006 - Elsevier
We interpret the discrepancy between semiempirical nuclear mass formulas and actual
nuclear masses in terms of the residual interaction. We show that correlations exist among …

Masses of atomic nuclei far from stability

J Barea, A Frank, JG Hirsch, P Van Isacker… - The European Physical …, 2007 - Springer
It is shown that a new way of applying a set of nuclear-mass relations among neighbouring
nuclei, known as the Garvey–Kelson (GK) relations, holds exceptionally well for all currently …

Ground state energy fluctuations in the nuclear shell model

V Velázquez, JG Hirsch, A Frank, J Barea, AP Zuker - Physics Letters B, 2005 - Elsevier
Statistical fluctuations of the nuclear ground state energies are estimated using shell model
calculations in which particles in the valence shells interact through well-defined forces, and …
