Landau parameters for energy density functionals generated by local finite-range pseudopotentials

Idini, A. LU orcid ; Bennaceur, K. and Dobaczewski, J. (2017) In Journal of Physics G: Nuclear and Particle Physics 44(6).
Abstract

In Landau theory of Fermi liquids, the particle-hole interaction near the Fermi energy in different spin-isospin channels is probed in terms of an expansion over the Legendre polynomials. This provides a useful and efficient way to constrain properties of nuclear energy density functionals in symmetric nuclear matter and finite nuclei. In this study, we present general expressions for Landau parameters corresponding to a two-body central local regularized pseudopotential. We also show results obtained for two recently adjusted NLO and N2LO parametrizations. Such pseudopotentials will be used to determine mean-field and beyond-mean-field properties of paired nuclei across the entire nuclear chart.
