  Title Landau sum rules with noncentral quasiparticle interactions Type Journal Article
  Year 2023 Publication Physical Review C Abbreviated Journal Phys. Rev. C  
  Volume 108 Issue 3 Pages 034003 - 7pp  
  Keywords  
  Abstract We derive explicit expressions for the Landau sum rules for the case of the most general spin-dependent quasiparticle interaction including all possible tensor interactions. For pure neutron matter, we investigate the convergence of the sum rules at different orders of approximation. Employing modern nuclear Hamiltonians based on chiral effective field theory, we find that the inclusion of noncentral interactions improves the convergence of the sum rules only for low densities (n <= 0.1 fm-3). Around nuclear matter saturation density, we find that even ostensibly perturbative nuclear interactions violate the sum rules considerably. By artificially weakening the strength of the nuclear Hamiltonian, the convergence can be improved.

  Title Skyrme effective pseudopotential up to the next-to-next-to-leading order Type Journal Article
  Year 2013 Publication Journal of Physics G Abbreviated Journal J. Phys. G  
  Volume 40 Issue 9 Pages 095104 - 8pp  
  Keywords  
  Abstract The explicit form of the next-to-next-to-leading order ((NLO)-L-2) of the Skyrme effective pseudopotential compatible with all required symmetries and especially with gauge invariance is presented in a Cartesian basis. It is shown in particular that for such a pseudopotential there is no spin-orbit contribution and that the D-wave term suggested in the original Skyrme formulation does not satisfy the invariance properties. The six new (NLO)-L-2 terms contribute to both the equation of state and the Landau parameters. These contributions to symmetric nuclear matter are given explicitly and discussed.

  Title Nuclear matter response function with a central plus tensor Landau interaction Type Journal Article
  Year 2014 Publication Journal of Physics G Abbreviated Journal J. Phys. G  
  Volume 41 Issue 5 Pages 055103 - 17pp  
  Keywords Landau; random phase approximation; phenomenological interactions; tensor  
  Abstract 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 tensor contributions. The response functions keep the explicit momentum dependence of the RPA, in contrast with the traditional Landau approximation. Results for symmetric nuclear matter and pure neutron matter are presented using Landau parameters derived from finite-range interactions, both phenomenological and microscopic. We study the convergence of response functions as the number of Landau parameters is increased.

  Title Fitting (NLO)-L-3 pseudo-potentials through central plus tensor Landau parameters Type Journal Article
  Year 2014 Publication Journal of Physics G Abbreviated Journal J. Phys. G  
  Volume 41 Issue 6 Pages 065104 - 12pp  
  Keywords Landau parameters; (NLO)-L-3; phenomenological interactions; fitting methods  
  Abstract Landau parameters determined from phenomenological finite-range interactions are used to get an estimation of next-to-next-to-next-to-leading order ((NLO)-L-3) pseudo-potentials parameters. The parameter sets obtained in this way are shown to lead to consistent results concerning saturation properties. The uniqueness of this procedure is discussed, and an estimate of the error induced by the truncation at (NLO)-L-3 is given.

  Title Linear response theory in asymmetric nuclear matter for Skyrme functionals including spin-orbit and tensor terms Type Journal Article
  Year 2014 Publication Physical Review C Abbreviated Journal Phys. Rev. C  
  Volume 89 Issue 4 Pages 044302 - 14pp  
  Keywords  
  Abstract The formalism of linear response theory for a Skyrme functional including spin-orbit and tensor terms is generalized to the case of infinite nuclear matter with arbitrary isospin asymmetry. Response functions are obtained by solving an algebraic system of equations, which is explicitly given. Spin-isospin strength functions are analyzed varying the conditions of density, momentum transfer, asymmetry, and temperature. The presence of instabilities, including the spinodal one, is studied by means of the static susceptibility.

  Title Tools for incorporating a D-wave contribution in Skyrme energy density functionals Type Journal Article
  Year 2015 Publication Journal of Physics G Abbreviated Journal J. Phys. G  
  Volume 42 Issue 3 Pages 034001 - 19pp  
  Keywords energy density functional; D-wave; Skyrme pseudo-potential; linear response theory  
  Abstract 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-next-to-leading order of the Skyrme pseudo-potential. The aim of the present article is to provide the necessary tools to incorporate this term in a fitting procedure: first, a mean-field equation written in spherical symmetry in order to describe spherical nuclei and second, the response function to detect unphysical instabilities. With these tools it will be possible to build a new fitting procedure to determine the coupling constants of the new functional.

  Title Linear response theory and neutrino mean free path using Brussels-Montreal Skyrme functionals Type Journal Article
  Year 2014 Publication Physical Review C Abbreviated Journal Phys. Rev. C  
  Volume 90 Issue 2 Pages 025804 - 11pp  
  Keywords  
  Abstract The Brussels-Montreal Skyrme functionals have been successful in describing properties of both finite nuclei and infinite homogeneous nuclear matter. In their latest version, these functionals have been equipped with two extra density-dependent terms in order to reproduce simultaneously ground state properties of nuclei and infinite nuclear matter properties while avoiding at the same time the arising of ferromagnetic instabilities. In the present article, we extend our previous results of the linear response theory to include such extra terms at both zero and finite temperature in pure neutron matter. The resulting formalism is then applied to derive the neutrino mean free path. The predictions from the Brussels-Montreal Skyrme functionals are compared with ab initio methods.

  Title Effect of three-body forces on response functions in infinite neutron matter Type Journal Article
  Year 2015 Publication Physical Review C Abbreviated Journal Phys. Rev. C  
  Volume 91 Issue 1 Pages 014323 - 7pp  
  Keywords  
  Abstract 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 from a residual interaction expressed in terms of Landau parameters. Special attention is paid to the noncentral part, including all terms allowed by the relevant symmetries. Using Landau parameters derived from realistic nuclear two-and three-body forces grounded in chiral effective field theory, we find that the three-body term has a strong impact on the excited states of the system and in the static and long-wavelength limit of the response functions for which a new exact formula is established.

  Title Partial wave decomposition of the N3LO equation of state Type Journal Article
  Year 2015 Publication Physica Scripta Abbreviated Journal Phys. Scr.  
  Volume 90 Issue 11 Pages 114002 - 6pp  
  Keywords nuclear structure; equation of state; effective theory  
  Abstract By means of a partial wave decomposition, we separate their contributions to the equation of state (EoS) of symmetric nuclear matter for the N3LO pseudo-potential. In particular, we show that although both the tensor and the spin-orbit terms do not contribute to the EoS, they give a non-vanishing contribution to the separate (JLS) channels.
