Skyrme N2LO pseudo-potential for calculations of properties of atomic nuclei
P. Becker, D. Davesne, J. Meyer +2
We present recent developments obtained in the so-called N2LO extension of the usual Skyrme pseudo-potential. In particular, we discuss the isovector splitting mass in infinite nuc…
Spurious finite-size instabilities in nuclear energy density functionals: spin channel
A. Pastore, D. Tarpanov, D. Davesne +1
It has been recently shown, that some Skyrme functionals can lead to non-converging results in the calculation of some properties of atomic nuclei. A previous study has pointed out…
Extended Skyrme pseudo-potential deduced from infinite matter properties
D. Davesne, J. Navarro, P. Becker +3
We discuss the contributions to the Equation of State for the NLO Skyrme pseudo-potential (=2,3). We show that by adding 4th and 6th order gradient terms, it is possibl…
Partial wave decomposition of the N3LO equation of state
D. Davesne, J. Meyer, A. Pastore +1
By means of a partial wave decomposition, we separate their contributions to the equation of state of symmetric nuclear matter for the N3LO pseudo-potential. In particular, we show…
Tools for incorporating a D-wave contribution in Skyrme energy density functionals
P. Becker, D. Davesne, J. Meyer +2
The possibility of adding a D-wave term to the standard Skyrme effective interaction has been widely considered in the past. Such a term has been shown to appear in the next-to-nex…
Spurious finite-size instabilities in nuclear energy density functionals
V. Hellemans, A. Pastore, T. Duguet +5
It is known that some well-established parametrizations of the EDF do not always provide converged results for nuclei and a qualitative link between this finding and the appearance…
Fitting Skyrme functionals using linear response theory
A. Pastore, D. Davesne, K. Bennaceur +2
Recently, it has been recently shown that the linear response theory in symmetric nuclear matter can be used as a tool to detect finite size instabilities for different Skyrme func…
Nuclear response for the Skyrme effective interaction with zero-range tensor terms. II. Sum rules and instabilities
A. Pastore, D. Davesne, Y. Lallouet +3
The formalism of linear response theory for Skyrme forces including tensor terms presented in article [1] is generalized for the case of a Skyrme energy density functional in infin…
Linear response in infinite nuclear matter as a tool to reveal finite size instabilities
A. Pastore, K. Bennaceur, D. Davesne +1
Nuclear effective interactions are often modelled by simple analytical expressions such as the Skyrme zero-range force. This effective interaction depends on a limited number of pa…
Non-empirical pairing energy density functional. First order in the nuclear plus Coulomb two-body interaction
T. Lesinski, T. Duguet, K. Bennaceur +1
We perform systematic calculations of pairing gaps in semi-magic nuclei across the nuclear chart using the Energy Density Functional method and a {\it non-empirical} pairing functi…
The Tensor Part of the Skyrme Energy Density Functional
Thomas Lesinski, Michael Bender, Karim Bennaceur +2
We systematically study the effect of the J^2 tensor terms in the Skyrme energy functional on properties of spherical nuclei. We build a set of 36 parameterizations covering a wide…
Some challenges for Nuclear Density Functional Theory
T. Duguet, K. Bennaceur, T. Lesinski +1
We discuss some of the challenges that the DFT community faces in its quest for the truly universal energy density functional applicable over the entire nuclear chart.
Microscopic approach to collective motion
P. Bonche, E. Chabanat, B. Q. Chen +7
An overview of a microscopic framework based on the Hartree-Fock description of the mean field is presented which, starting from an effective interaction allows a description of co…
