Error analysis of the parameters of the Skyrme N2LO pseudo-potential
P. Becker, A. Pastore, D. Davesne +1
We perform a detailed analysis of the parameters of the Skyrme SN2LO interaction. By mean of a covariance matrix analysis, we have been able to provide error bars and build the com…
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…
Two-body contributions to the effective mass in nuclear effective interactions
D. Davesne, J. Navarro, J. Meyer +2
Starting from general expressions of well-chosen symmetric nuclear matter quantities derived for both zero- and finite-range effective theories, we derive the contributions to the…
Does the Gogny interaction need a third Gaussian?
D. Davesne, P. Becker, A. Pastore +1
By considering infinite matter constraints only, we suggest in this paper that the Gogny interaction should benefit from a third Gaussian in its central part. A statistical analysi…
Infinite matter properties and zero-range limit of nonrelativistic finite-range interactions
D. Davesne, P. Becker, A. Pastore +1
We discuss some infinite matter properties of two finite-range interactions widely used for nuclear structure calculations, namely Gogny and M3Y interactions. We show that some use…
Partial wave decomposition of finite-range effective tensor interaction
D. Davesne, P. Becker, A. Pastore +1
We perform a detailed analysis of the properties of the finite-range tensor term associated with the Gogny and M3Y effective interactions. In particular, by using a partial wave de…
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…
Effect of three-body forces on response functions in infinite neutron matter
D. Davesne, J. W. Holt, A. Pastore +1
We study the impact of three-body forces on the response functions of cold neutron matter. These response functions are determined in the random phase approximation (RPA) from a re…
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…
Nuclear matter response function with a central plus tensor Landau interaction
A. Pastore, D. Davesne, J. Navarro
We present a method to obtain response functions in the random phase approximation (RPA) based on a residual interaction described in terms of Landau parameters with central plus t…
Skyrme effective pseudopotential up to next-to-next-to leading order
D. Davesne, A. Pastore, J. Navarro
The explicit form of the next-to-next-to-leading order (N2LO) of the Skyrme effective pseudopotential compatible with all required symmetries and especially with gauge invariance i…
Neutron Fermi Liquids under the presence of a strong magnetic field with effective nuclear forces
M. Angeles Perez-Garcia, J. Navarro, A. Polls
Landau's Fermi Liquid parameters are calculated for non-superfluid pure neutron matter in the presence of a strong magnetic field at zero temperature. The particle-hole interaction…
