Isospin dependent properties of asymmetric nuclear matter — •Urnaa Badarch and Horst Lenske — Institut für Theoretische Physik, Universität Giessen
The study of the density dependence of the nuclear symmetry energy is very important for understanding many phenomena in both nuclear physics and astrophysics. We study the isospin dependence of in-medium nuclear effective interactions and the equation of state of neutron-rich nuclear matter, i.e., the density dependence of nuclear symmetry energy using the relativistic density-dependent hadron-field theory (DDRH). The DDRH approach allows a fully self-consistent calculation of the equation of state and the symmetry energy at any proton-to-neutron fraction on a fully microscopic level. We present the results of our calculation for the density dependence of nuclear symmetry energy focusing on the features such as an isospin effects in nuclear matter and behavior at low and high density.
