Thermal effects in hot and dilute homogeneous asymmetric nuclear matter

چکیده

We present a comprehensive analysis of hot and dilute isospin-asymmetric nuclear matter employing the temperature-dependent effective-relativistic mean-field theory (E-RMF). The E-RMF is applied to study effect $\delta$ $\omega-\rho$ meson cross-coupling on thermal properties asymmetric using two recently developed IOPB-I G3 parameter sets. These sets are known reproduce in agreement with various experimental observational constraints. consider be homogeneous equation state (EoS) for densities, temperature asymmetry which relevant astrophysical simulations such as supernovae explosion. investigated reference density-dependent free symmetry energy its higher-order derivatives well parabolic approximation. larger value $\lambda_\omega$ addition coupling smoothen energy. Thermal effects variables examined at fixed isospin by separating their T=0 finite-T expressions. mainly governed effective mass estimating contribution. isothermal isentropic incompressibility discussed harmony available microscopic calculations. liquid-gas phase transition conserved charges context different slope comparable set. spinodal instability, binodal curve critical found influenced $L_{sym}$.

Correlations in hot asymmetric nuclear matter

The single-particle spectral functions in asymmetric nuclear matter are computed using the ladder approximation within the theory of finite temperature Green’s functions. The internal energy and the momentum distributions of protons and neutrons are studied as a function of the density and the asymmetry of the system. The proton states are more strongly depleted when the asymmetry increases whe...

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...

Symmetry energy of dilute warm nuclear matter.

The symmetry energy of nuclear matter is a fundamental ingredient in the investigation of exotic nuclei, heavy-ion collisions, and astrophysical phenomena. New data from heavy-ion collisions can be used to extract the free symmetry energy and the internal symmetry energy at subsaturation densities and temperatures below 10 MeV. Conventional theoretical calculations of the symmetry energy based ...

Stability and instability of a hot and dilute nuclear droplet

The diabatic approach to collective nuclear motion is reformulated in the local-density approximation in order to treat the normal modes of a spherical nuclear droplet analytically. In a first application the adiabatic isoscalar modes are studied and results for the eigenvalues of compressional (bulk) and pure surface modes are presented as function of density and temperature inside the droplet...
