Spinodal instabilities in nuclear matter in a stochastic relativistic mean-field approach

Journal Article Ayik, S ; Yilmaz, O ; Er, N ; ... - Physical Review. C, Nuclear Physics

Spinodal instabilities and early growth of baryon density fluctuations in symmetric nuclear matter are investigated in the basis of the stochastic extension of the relativistic mean-field approach in the semiclassical approximation. Calculations are compared with the results of nonrelativistic calculations based on Skyrme-type effective interactions under similar conditions. A qualitative difference appears in the unstable response of the system: the system exhibits most unstable behavior at higher baryon densities around {rho}{sub b}=0.4{rho}{sub 0} in the relativistic approach while most unstable behavior occurs at lower baryon densities around {rho}{sub b}=0.2{rho}{sub 0} in the nonrelativistic calculations.

Spinodal instabilities and the distillation effect in nuclear matter under strong magnetic fields

Journal Article Rabhi, A ; Laboratoire de Physique de la Matiere Condensee, Faculte des Sciences de Tunis, Campus Universitaire, Le Belvedere-1060 ; Providencia, C ; ... - Physical Review. C, Nuclear Physics

We study the effect of strong magnetic fields, of the order of 10{sup 18}-10{sup 19} G, on the instability region of nuclear matter at subsaturation densities. Relativistic nuclear models both with constant couplings and with density-dependent parameters are considered. It is shown that a strong magnetic field can have large effects on the instability regions giving rise to bands of instability and wider unstable regions. As a consequence, we predict larger transition densities at the inner edge of the crust of compact stars with strong magnetic fields. The direction of instability gives rise to a very strong distillation effect ifmore »« less

Effect of memory time on the agitation of unstable modes in nuclear matter

Journal Article Ayik, S ; Randrup, J - Physical Review, C (Nuclear Physics); (United States)

The spontaneous agitation of collective modes in unstable nuclear matter is addressed with an extended Boltzmann-Langevin (BL) theory that incorporates a memory time in the stochastic force. The growth of the modes is then governed by effective diffusion coefficients which are renormalized by time-dependent factors, relative to the standard treatment. These correction factors deviate significantly from unity in the most unstable domain of the density-temperature phase plane, indicating the importance of including a memory time in numerical BL simulations of nuclear dynamics.

Instabilities in asymmetric nuclear matter

Journal Article Avancini, S S ; Menezes, D P ; Brito, L ; ... - Physical Review. C, Nuclear Physics

The existence of phase transitions from liquid to gas phases in asymmetric nuclear matter (ANM) is related with the instability regions which are limited by the spinodals. In this work we investigate the instabilities in ANM described within relativistic mean field hadron models, both with constant and density dependent couplings at zero and finite temperatures. In calculating the proton and neutron chemical potentials we have used an expansion in terms of Bessel functions that is convenient at low densities. The role of the isovector scalar {delta}-meson is also investigated in the framework of relativistic mean field models and density dependentmore »« less
