Landau parameters with effective nucleon-nucleon interactions — •Haris DJapo¹, Robert Roth¹, Bernd-Jochen Schaefer², and Jochen Wambach^1,3 — ¹Institut für Kernphysik, TU Darmstadt, Schloßgartenstr. 9, D-64289 Darmstadt,Germany — ²Institut für Physik, Karl-Franzens-Universität Graz, Universitätsplatz 5, A-8010 Graz, Austria — ³Gesellschaft für Schwerionenforschung mbH, Planckstr. 1, D-64291 Darmstadt, Germany

Using recently developed effective nucleon-nucleon interactions we investigate properties of nuclear matter. A comparison of basic properties of effective low momentum potential V_{low k} and a potential constructed with unitary correlation operators V_UCOM in uniform nuclear matter is presented. Energy per particle, single-particle potentials, nucleon effective masses and Landau parameters are calculated and analyzed as a function of density for both nuclear and neutron matter. By introducing the density-dependent force we mimic the missing influence of higher order interactions to the properties of nuclear matter.
