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:

Construction of matter models which violate the strong energy condition and may avoid the initial singularity
TL;DR: In this paper, Lagrangians of matter models with interaction are constructed, which induce a violation of the strong energy condition, and the question of whether the initial singularity is avoidable in this context is of particular interest.

Optimized δ expansion for the Walecka model
TL;DR: The optimized δ-expansion is used to study vacuum polarization effects in the Walecka model and, using the same set of parameters that saturate nuclear matter in the RHA, a new stable, tightly bound state at high density is found.
Journal ArticleDOI
Magnetic moments of octet baryons in hot and dense nuclear matter
TL;DR: In this article, the in-medium magnetic moments of octet baryons in the presence of hot and dense symmetric nuclear matter have been derived from medium modified quark masses within chiral SU(3) quark mean field model.
Journal ArticleDOI
Axial currents in nuclei in the framework of the sigma model
TL;DR: In this article, the axial-vector coupling constant in nuclear matter due to the scalar ǫ − Ψ Ψ − condensate suppression is considered in the framework of the modified sigma model.
Journal ArticleDOI
Pion-condensed nuclear matter at finite temperatures
TL;DR: The possibility of density isomers in nuclear matter, induced by pion condensation, with special regard to heavy-ion collisions, is discussed in this article, where the equation of state of the combined system of baryons and pions is treated within the framework of the linear σ-model.

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.
Journal ArticleDOI
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.
