Three-dimensional Yukawa models and CFTs at strong and weak couplings
TL;DR: In this article, the massless three-dimensional Gross-Neveu-Yukawa (GNY) and Nambu-Jona-Lasinio-YUKawa (NJLY) models at finite temperatures are analyzed within the mean field framework considering all coupling values.

Canonical transformation path to gauge theories of gravity II --- Spacetime coupling of spin-0 and spin-1 particle fields
Juergen Struckmeier,J. Muench,P. Liebrich,Matthias Hanauske,J. Kirsch,D. Vasak,L. Satarov,Horst Stoecker +7 more
TL;DR: In this article, the authors discussed the coupling of the gravitational field with a massive complex scalar field, a massive real vector field, and a massless vector field and showed that different couplings emerge for massive and non-massive vector fields.

Phase transition to quark matter in neutron stars
TL;DR: In this article, the critical density ϱ t at which it is more favorable for the matter to be in the quark phase than in the nuclear one was calculated, assuming that the QCD effective lagrangian satisfactorily describes the interaction at all energies and making a relativistic Hartree-Fock approximation.

Behaviour of the centrifugal force and of ellipticity for a slowly rotating fluid configuration with different equations of state
TL;DR: In this paper, the authors evaluated the centrifugal force acting on a fluid element and the ellipticity of the fluid configuration, which is slowly rotating, using the Hartle - Thorne solution for different equations of state.

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.
