Relativistic Stellar Models with Quadratic Equation of State

In this paper, we have obtained and presented new relativistic stellar configurations considering an anisotropic fluid distribution with a charge distribution and a gravitational potential Z(x) that depends on an adjustable parameter. The quadratic equation of state based on Feroze and Siddiqui viewpoint is used for the matter distribution. The new solutions can be written in terms of elementar...

A Cosmological Model Describing the Early Inflation, the Intermediate Decelerating Expansion, and the Late Accelerating Expansion of the Universe by a Quadratic Equation of State

We develop a cosmological model based on a quadratic equation of state p/c = −(α + 1)ρ/ρP + αρ− (α + 1)ρΛ, where ρP is the Planck density and ρΛ the cosmological density, “unifying” vacuum energy and dark energy in the spirit of a generalized Chaplygin gas model. For ρ → ρP , it reduces to p = −ρP c leading to a phase of early accelerating expansion (early inflation) with a constant density equ...

The Standard Cosmological Model

We have a well-established standard model for cosmology and prospects for considerable additions from work in progress. I offer a list of elements of the standard model, comments on controversies in the interpretation of the evidence in support of this model, and assessments of the directions extensions of the standard model seem to be taking. Table of

The Standard Cosmological Model

The Standard Model of Particle Physics (SMPP) is an enormously successful description of high energy physics, driving ever more precise measurements to find ‘physics beyond the standard model’, as well as providing motivation for developing more fundamental ideas that might explain the values of its parameters. Simultaneously, a description of the entire 3-dimensional structure of the present-d...

Dirac Equation in Standard Cosmological Models

The time equation associated to the Dirac Equation (DE) is studied for the radiation-dominated Friedmann-Robertson-Walker (FRW) universe. The results are analysed for small and large values of time. We also incorporate the corrections of the paper studied by Zecca [1] for the matter-dominated FRW universe. PACS 03.65.Pm-Relativistic wave equations. PACS 04.62-Quantum field theory in curved spac...
