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 ... -
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 ... -
Prompt and delayed spectroscopy of 203At : Observation of a shears band and a 29/2+ isomeric state
Auranen, Kalle; Uusitalo, Juha; Juutinen, Sakari; Badran, Hussam; Bisso, F. Defranchi; Cox, Daniel; Grahn, Tuomas; Greenlees, Paul; Herzan, Andrej; Jakobsson, U.; Julin, Rauno; Konki, Joonas; Leino, Matti; Lightfoot, A.; Mallaburn, M. J.; Neuvonen, O.; Pakarinen, Janne; Papadakis, Philippos; Partanen, Jari; Rahkila, Panu; Sandzelius, Mikael; Sarén, Jan; Scholey, Catherine; Sorri, Juha; Stolze, Sanna; Wang, Y. K. (American Physical Society, 2018)Using fusion-evaporation reactions, a gas-filled recoil separator, recoil-gating technique and recoil-isomer decay tagging technique we have extended the level scheme of 203 At ( N = 118 ) significantly. We have ... -
Response calculations based on an independent particle system with the exact one- particle density matrix: Excitation energies
Giesbertz, Klaas; Gritsenko, O. V.; Baerends, E. J. (American Institute of Physics, 2012)Adiabatic response time-dependent density functional theory (TDDFT) suffers from the restriction to basically an occupied → virtual single excitation formulation. Adiabatic time-dependent density matrix functional theory ... -
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 ...
