A theory of highly condensed matter
TLDR
In this article, a model relativistic, many-body, quantum field theory composed of a baryon field, a neutral scalar meson field coupled to the scalar density ψ ψ, and a neutral vector meson fields coupled with the conserved Baryon current i Ψ γλψ is developed.About:

Recent progress on superstrange dynamics
TL;DR: The status of theoretical predictions and experimental evidences for the in-medium formation of bound superstrange matter is discussed in this article, where heavy-ion collisions and antiproton-induced reactions at energies close to strangeness production thresholds create the conditions of hypermatter formation.

Scalar-isovector δ meson in the relativistic mean field theory and the structure of neutron stars with a quark core
TL;DR: In this paper, the effect of the δ meson field on the characteristics of a Maxwell-type quark phase transition has been studied in the framework of relativistic mean field theory.

Collective effects on transport coefficients of relativistic nuclear matter.
Rémi Hakim,Lysiane Mornas +1 more
TL;DR: The Walecka's model of nuclear matter is studied, where the meson fields contribute to the various observables in the Hartree approximation only while all correlations give rise to a collision term considered in the relaxation-time approximation.
Journal ArticleDOI
Configuration mixing calculation for complete low-lying spectra with a mean-field Hamiltonian
TL;DR: In this paper, a new theoretical approach to ground and low-energy excited states of nuclei extending the nuclear mean field theory is proposed, which consists of three steps: stochastic preparation of many Slater determinants, the parity and angular-momentum projection, and diagonalization of the generalized eigenvalue problems.

An example of the interplay of nonextensivity and dynamics in the description of QCD matter
TL;DR: In this paper, the authors investigated the interplay between the dynamical content of fugacities and effects induced by nonextensivity in situations when this model is used in a nonextensive environment characterized by some nonextense parameter q $
eq$ 1 (for the usual extensive case q=1).

On Massive neutron cores
J. R. Oppenheimer,G. M. Volkoff +1 more
TL;DR: In this paper, the authors studied the gravitational equilibrium of masses of neutrons, using the equation of state for a cold Fermi gas, and general relativity, and showed that for masses under 1/3, there are no static equilibrium solutions.

Static Solutions of Einstein's Field Equations for Spheres of Fluid
TL;DR: In this article, a method is developed for treating Einstein's field equations, applied to static spheres of fluid, in such a manner as to provide explicit solutions in terms of known analytic functions.

On Continued Gravitational Contraction
TL;DR: In this paper, the authors study the solutions of the gravitational field equations which describe the contraction of a heavy star, and give general and qualitative arguments on the behavior of the metrical tensor as the contraction progresses.
