Temperature dependence of nuclear matter generalized isovector symmetry energy with Skyrme-type interactions

Abstract

The temperature dependence of the nuclear matter isovector symmetry energy coefficient (A 0,1 ) is investigated in the framework of the generalized nuclear polarizability with Skyrme interactions, as worked out in previous articles [F. L. Braghin, Nucl. Phys. A665, 13 (2000); Phys Rev. C 71, 064303 (2005); Int J. Mod. Phys. E 12, 755 (2003)]. The variation of A 0,1 (T ) is very small (of the order of 1 MeV) for temperatures (T ) in the range of 0 and 18 MeV. Different behaviors with temperature are found to strongly depend on the Skyrme parametrization, in particular at densities lower than the saturation density ρ 0 .

“…The relatively weak T dependence of the symmetry energy extracted from the experimental data in Fig. 3 is in agreement with most theoretical predictions [58,54,59,60,61,62,63,64]. However, a more detailed account of the theoretical approaches and results addressing the temperature dependence of the symmetry energy is presented in this special EPJA issue by Agrawal et al.…”

“…In recent years, there has been an increasing interest in the study of symmetry energy and properties of neutron stars at finite temperature [24][25][26][27][28][29][30][31][32]. While the effect of temperature on the kinetic energy part of E S (ρ, T ) is well understood [33][34][35][36], the temperature dependence of the interaction part of the symmetry energy has received less attention [30,31,37,38]. Most of these works in this context have been accomplished in the framework of non-relativistic mean field theory using effective interactions.…”
