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-isospin stability of nuclear matter

We calculate the density-dependent spin-isospin asymmetry energy J(kf ) of nuclear matter in the three-loop approximation of chiral perturbation theory. The interaction contributions to J(kf ) originate from one-pion exchange, iterated one-pion exchange, and irreducible two-pion exchange with no, single, and double virtual ∆-isobar excitation. We find that the approximation to 1π-exchange and i...

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...
