Thermodynamic behavior of the generalized scalar Yukawa model in a magnetic background
Luciano M. Abreu,A. P. C. Malbouisson,Jorge Mário Carvalho Malbouisson,E. S. Nery,R. Rodrigues da Silva +4 more
TL;DR: In this paper, the authors studied the thermodynamic behavior of generalized scalar Yukawa model, composed of a complex scalar field interacting with scalar and vector fields, and analyzed the phase structure of this model at effective chemical equilibrium under change of values of the relevant parameters.

A connection between the relativistic mean field approach and effective interactions
A. Bouyssy,Sylvie Marcos +1 more
TL;DR: In this paper, the Dirac equation is reduced to a Schrodinger equation which resembles very much the Hartree-Fock-Skyrme equation and the connection with effective hamiltonians is discussed.

Shape coexistence and parity doublet in Zr isotopes
TL;DR: In this paper, the ground and excited states properties of Zr isotopes are studied from proton to neutron drip lines using the relativistic (RMF) and nonrelativistic mean-field formalisms with Bardeen-Cooper-Schrieffer (BCS) and Bogoliubov pairing, respectively.

A modified relativistic Hartree approximation to the nuclear matter equation of state
Erik K. Heide,Serge Rudaz +1 more
TL;DR: In this article, the renormalization scale of the Walecka σ - ω model is set to the effective nucleon mass at nuclear saturation density and the model gives a dramatically lower compression modulus.

Nuclear Matrix Elements of Axial-Charge Exchange Currents Derived in Heavy-Fermion Chiral Perturbation Theory
TL;DR: In this article, the shell-model matrix elements of the axial-charge exchange current operators were obtained up to the next-to-leading order from heavy-fermion chiral perturbation 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.
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.
