© 2015 The Physical Society of Japan. This is a final draft version of an article whose final and definitive form has been published by The Physical Society of Japan. Published in this repository with the kind permission of the publisher.
The parameters of the unedf2 nuclear energy density functional (EDF) model were obtained in an
optimization to experimental data consisting of nuclear binding energies, proton radii, odd-even mass
staggering data, fission-isomer excitation energies, and single particle energies. In addition to parameter
optimization, sensitivity analysis was done to obtain parameter uncertainties and correlations.
The resulting unedf2 is an all-around EDF. However, the sensitivity analysis also demonstrated that
the limits of current Skyrme-like EDFs have been reached and that novel approaches are called for.

Impact of the surface energy coefficient on the deformation properties of atomic nuclei as predicted by Skyrme energy density functionals
Ryssens, W.; Bender, M.; Bennaceur, Karim; Heenen, P.-H.; Meyer, J. (American Physical Society, 2019)Background: In the framework of nuclear energy density functional (EDF) methods, many nuclear phenomena are related to the deformation of intrinsic states. Their accurate modeling relies on the correct description of the ... -
Towards a novel energy density functional for beyond-mean-field calculations with pairing and deformation
Haverinen, Tiia; Kortelainen, Markus; Dobaczewski, J.; Bennaceur, K. (Jagellonian University, 2019)We take an additional step towards the optimization of the novel finite-range pseudopotential at a constrained Hartree–Fock–Bogolyubov level and implement an optimization procedure within an axial code using harmonic ... -
Model nuclear energy density functionals derived from ab initio calculations
Salvioni, G.; Dobaczewski, J.; Barbieri, C.; Carlsson, G.; Idini, A.; Pastore, A. (Institute of Physics, 2020)We present the first application of a new approach, proposed in (2016J.Phys.G:Nucl.Part.Phys.4304LT01) to derive coupling constants of the Skyrme energy density functional (EDF) fromab initioHamiltonian. By perturbing theab ... -
Approximate energy functionals for one-body reduced density matrix functional theory from many-body perturbation theory
Giesbertz, Klaas J. H.; Uimonen, Anna-Maija; van Leeuwen, Robert (Springer, 2018)We develop a systematic approach to construct energy functionals of the one-particle reduced density matrix (1RDM) for equilibrium systems at finite temperature. The starting point of our formulation is the grand potential ... -
