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 ($\cA_{0,1}$) is investigated in the framework of the generalized nuclear polarizability with Skyrme interactions, as worked out in Refs. \cite{npa,prc}. The variation of $\cA_{0,1}(T)$ 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 strongly depending on the Skyrme parameterization, in particular at densities lower than the saturation density $\rho_0$.
