چکیده

Based on the Hugenholtz–Van Hove theorem, six basic quantities of EoS in isospin asymmetric nuclear matter are expressed terms nucleon kinetic energy t(k), symmetric and parts single-nucleon potentials $$U_0(\rho ,k)$$ $$U_{\text {sym},i}(\rho . The include quadratic symmetry $$E_{\text {sym,2}}(\rho )$$ , quartic {sym,4}}(\rho their corresponding density slopes $$L_2(\rho $$L_4(\rho incompressibility coefficients $$K_2(\rho $$K_4(\rho By using four types well-known effective nucleon–nucleon interaction models, namely BGBD, MDI, Skyrme, Gogny forces, density- isospin-dependent properties these systematically calculated values at saturation $$\rho _0$$ explicitly given. contributions to from also analyzed normal It is clearly shown that first-order term {sym,1}}(\rho (also known as potential Lane potential) plays a vital role determining dependence high-order ( with $$i>1$$ ) cannot be neglected calculations other five quantities. Moreover, by analyzing exact _{\text {sat}}(\delta coefficient found have simple empirical relation $$K_{\text {sat,2}}=K_{2}(\rho _0)-4.14 L_2(\rho _0)$$

Equation of state of isospin-asymmetric nuclear matter in relativistic mean-field models with chiral limits

Using in-medium hadron properties according to the Brown-Rho scaling due to the chiral symmetry restoration at high densities and considering naturalness of the coupling constants, we have newly constructed several relativistic mean-field Lagrangians with chiral limits. The model parameters are adjusted such that the symmetric part of the resulting equation of state at supra-normal densities is...

Chemical and mechanical instability in hot isospin - asymmetric nuclear matter

Using phenomenological equations of state, we study the chemical and mechanical instabilities in hot isospin-asymmetric nuclear matter. Both instabilities are found to depend strongly on the isospin asymmetry of the nuclear matter. For a chemically and mechanically stable asymmetric nuclear matter, a lower neutron excess is found in the liquid phase than in the gas phase. Furthermore, the neutr...

Pseudo-Goldstone Modes in Isospin-Asymmetric Nuclear Matter

We analyze the chiral limit in dense isospin-asymmetric nuclear matter. It is shown that the pseudo-Goldstone modes in this system are qualitatively different from the case of isospin-symmetric matter.

Spin and Isospin Asymmetry, Equation of State and Neutron Stars

In the present work, we have obtained the equation of state for neutron star matter considering the in uence of the ferromagnetic and antiferromagnetic spin state. We have also investigated the structure of neutron stars. According to our results, the spin asymmetry stiens the equation of state and leads to high mass for the neutron star.

Symmetry Energy in the Equation of State of Asymmetric Nuclear Matter

The symmetry energy is an important quantity in the equation of state of isospin asymmetric nuclear matter. This currently unknown quantity is key to understanding the structure of systems as diverse as the neutron-rich nuclei and neutron stars. At TAMU, we have carried out studies, aimed at understanding the symmetry energy, in a variety of reactions such as, the multifragmentation of Here we ...
