Description
We used the Relativistic Hartree-Fock theory to calculate the equation of state (EOS) of spin-polarized matter, where the spins of nucleons are biased either up or down. Similar to the slope parameter of the isospin-symmetry energy in spin unpolarized matter, we define the “spin slope parameter” of the spin-symmetry energy to characterize the variation of the energy as the spin polarization is varied. In this contribution, we will discuss the correlation between the slope parameters and the spin slope parameters in varying the parameter sets. We will show that the slope parameters and the spin slope parameters have a negative correlation when neutrons and protons are spin-polarized along the same direction, while the spin slope parameter is nearly independent of the slope parameter when neutrons are spin-polarized along the opposite direction to protons.
