Title: Collective modes in relativistic asymmetric nuclear matter

Abstract

Isospin and density waves in asymmetric nuclear matter (ANM) are studied in the framework of relativistic mean-field hadron models. A semiclassical relativistic approach based on the Vlasov equation is applied to the study of infinite asymmetric nuclear matter. The isovector and isoscalar collective modes are determined for a wide range of densities as a function of isospin asymmetry and momentum transfer. The condition for the existence of each type of mode is referred. The instabilities of ANM, related to the liquid-gas phase transition, are investigated.
