Predictions in the superheavy region from the quark-meson coupling model QMCπ-III

Kay Marie M. Paglinawan, A. W. Thomas, P.A.M. Guichon, J. R. Stone

The Quark-Meson Coupling (QMC) model establishes a self-consistent relationship between the quark structure dynamics of a nucleon and the relativistic mean fields that arise within the nuclear medium [1]. The model has been successful in calculating the ground-state observables of finite nuclei …

Nuclear Symmetry Energy in Strongly Interacting Matter: Past, Present and Future

J. R. Stone

The concept of symmetry under various transformations of quantities describing basic natural phenomena is one of the fundamental principles in the mathematical formulation of physical laws. Starting with Noether’s theorems, we highlight some well–known examples of global symmetries and symmetry breaking on …

Hartree-Fock formulation of the QMC model at finite temperature

P.A.M. Guichon, J. R. Stone, A. W. Thomas

A first application of the equation of state (EoS) in the quark-meson-coupling (QMC) model in thermodynamic scenarios corresponding to stationary and rotating isentropic protoneutron stars (PNS), producing results in agreement with recent observation, was published recently. In addition, a tabulated form of …

Proton and neutron density distributions at supranormal density in low- and medium-energy heavy-ion collisions. II. Central Pb + Pb collisions

J. R. Stone, Paweł Danielewicz, Yoritaka Iwata

This paper represents a continuation of our investigation into the limitations on total, proton, and neutron particle number densities, as well as the asymmetry of proton and neutron density distributions achievable in central heavy-ion collisions. We explore these aspects at low and …

Coulomb and symmetry-energy effects on proton and neutron density-distributions in central heavy-ion collisions, across beam energies and system masses

J. R. Stone, Paweł Danielewicz, Yoritaka Iwata

In this contribution, we review our current and previous investigations of total, proton, and neutron particle number densities and the asymmetry of proton and neutron density distributions achievable in central heavy-ion collisions at beam energy below 800 MeV/nucleon. Furthermore, the effects of …

Hartree-Fock Formulation of the QMC Model at Finite Temperature

P.A.M. Guichon, J. R. Stone, A. W. Thomas

We present, for the first time, a detailed theory of high density matter including the entire baryon octet at finite temperature, based on a fully relativistic mean field model with a consistent treatment of exchange (Fock) terms, using the quark-meson-coupling model (QMC). …

A Powerful New Energy Density Functional

A. W. Thomas, P.A.M. Guichon, J.Y.Y. Leong, K. L. Martinez-Paglinawan et autres

Abstract We describe the most recent energy density functional derived within the quark-meson coupling model. Although fit to the binding energies and charge radii of just seventy magic nuclei, the accuracy with which it reproduces nuclear properties across the entire periodic table …

Neutron stars: The journey from birth to death.

J. R. Stone

This paper contains the synopsis of my three lectures given at the XV International Workshop on Hadron Physics. The first lecture covers introduction to the general life cycle of stars and the origin of compact objects, followed by the history of neutron …

Nuclear Symmetry Energy and Hyperonic Stars in the QMC Model

J. R. Stone, P.A.M. Guichon, A. W. Thomas

The nuclear symmetry energy, together with the other saturation properties of symmetric nuclear matter, plays an important role in low energy nuclear structure of terrestrial systems, as well as astrophysical objects. In particular, its density dependence, both in sub- and supra-saturation regions …

Glassy quantum nuclear pasta in neutron star crusts

William G. Newton, Sarah Cantu, Shuxi Wang, Amber Stinson et autres

Nuclear pasta is an exotic form of nuclear matter that occurs in the crust of neutron stars below saturation density. Various exotic nuclear structures with cylindrical, planar, and more complicated geometries evolve from the Coulomb lattice of nuclei immersed in a fluid …
