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:

Dibaryon model for nuclear force and the properties of the 3N system
TL;DR: In this article, a new multicomponent formalism is developed to describe three-body systems with nonstatic pairwise interactions and nonnucleonic degrees of freedom, and a new Coulomb 3N force between the third nucleon and dibaryon is found for a correct description of the Coulomb energy and rms charge radius in 3He.

QCD sum rules at finite density in the large-Nc limit: the coupling of the ρ-nucleon system to the D13(1520)
Stefan Leupold,Marcus Post +1 more
TL;DR: In this article, the vector-isovector current at finite baryon density in the limit of large number of colors N c was studied and it was shown that in this limit the four-quark condensate factorizes also for the finite density case.

On pseudospin symmetry of Dirac states
Karl-Erik Thylwe,Majid Hamzavi +1 more
TL;DR: In this paper, it was shown that positive-energy pseudospin symmetric Dirac states exist in relativistic quantum mechanics, but not in the Schrodinger theory.

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.
