Contribution

It applies the LOCV technique to finite temperature nuclear matter, providing new insights into the effects of spin polarization and asymmetry on its thermodynamic behavior.

Findings

Symmetry energy is highly sensitive to spin polarization.

Equation of state becomes stiffer with increased polarization.

No spontaneous ferromagnetic phase transition occurs in hot asymmetric matter.

Abstract

The lowest order constrained variational (LOCV) technique has been used to investigate some of the thermodynamic properties of spin polarized hot asymmetric nuclear matter, such as the free energy, symmetry energy, susceptibility and equation of state. We have shown that the symmetry energy of the nuclear matter is substantially sensitive to the value of spin polarization. Our calculations show that the equation of state of the polarized hot asymmetric nuclear matter is stiffer for the higher values of the polarization as well as the isospin asymmetry parameter. Our results for the free energy and susceptibility show that the spontaneous ferromagnetic phase transition cannot occur for hot asymmetric matter.
