Kaon condensation in neutron star using relativistic mean field models
We use the modified quark-meson coupling and the quantum hadrodynamics models to study the properties of neutron star. Coupling constants of both models are adjusted to reproduce the same saturation properties. The onset of kaon condensation in neutron star matter is studied in detail over a wide range of kaon optical potential values. Once the kaon condensation takes place, the population of k...
متن کاملOptimization in mean field models
The non-rigorous cavity method of statistical mechanics, originally developed in the study of spin glasses and other disordered systems, has led to a number of purely mathematical predictions. Several of them can be found in the remarkable book [17] by Marc Mézard, Giorgio Parisi and Miguel Angel Virasoro. Establishing these predictions rigorously remains a challenge to probability theory. Impo...
متن کاملSensitivity of neutron radii in a Pb nucleus and a neutron star to nucleon-sigma-rho coupling corrections in relativistic mean field theory
Abstract We study the sensitivity of the neutron skin thickness, S, in a 208Pb nucleus to the addition of nucleon-sigma-rho coupling corrections to a selection (PK1, NL3, S271, Z271) of interactions in relativistic mean field model. The PK1 and NL3 effective interactions lead to a minimum value of S = 0.16 fm in comparison with the original value of S = 0.28 fm. The S271 and Z271 effective inte...
متن کاملNeutron radii in nuclei and the neutron equation of state.
The root-mean-square radius for neutrons in nuclei is investigated in the Skyrme Hartree-Fock model. The main source of theoretical variation comes from the exchange part of the density-dependent interaction which can be related to a basic property of the neutron equation of state. A precise measurement of the neutron radius in 208Pb would place an important new constraint on the equation of st...
