Quark-hadron phase transitions in the viscous early universe

  author={A. Tawfik and Tiberiu Harko},
  journal={Physical Review D},
In the standard hot big bang theory, when the Universe was about 1 10 �s old, the cosmological matter is conjectured to undergo Quantum Chromodynamics (QCD) phase transition(s) from quark matter to hadrons. In the present work, we study the cosmological quark-hadron phase transition in two different physical scenarios. First, by assuming that the phase transition would be described by an effective nucleation theory (prompt first-order phase transition), we analyze the evolution of the relevant… 

Early Universe Thermodynamics and Evolution in Nonviscous and Viscous Strong and Electroweak Epochs: Possible Analytical Solutions

The possible influence of the bulk viscosity in the early Universe is determined and the rate of decreasing H(a(t)) with increasing a(t) varies from epoch to epoch, at vanishing and finite cosmological constant.

Nuclear matter in the early universe

Recently, extreme conditions have been obtained in ultra-relativistic heavy ion collisions at RHIC and at the Large Hadron collider. It is believed that these conditions are similar to the ones of

QCD phase transition with a power law chameleon scalar field in the bulk

In this paper, a braneworld model with a perfect fluid on brane and a scalar field on bulk has been used to study quark–hadron phase transition. The bulk scalar field has an interaction with brane

Quark-hadron phase transition in DGP including BD brane

A Dvali–Gabadadze–Porrati (DGP) brane-world model with perfect fluid brane matter including a Brans-Dicke (BD) scalar field on brane was utilized to investigate the problem of the quark-hadron phase

Cosmic Evolution of Viscous QCD Epoch in Causal Eckart Frame

It is conjectured that in cosmological applications the particle current is not modified but finite heat or energy flow. Therefore, comoving Eckart frame is a suitable choice, as it merely ceases the

Equation of state for cosmological matter at and beyond QCD and electroweak eras

Various thermodynamic quantities for baryon-free matter are calculated by combining the most reliable non-perturbative and perturbative calculations, especially the most recent ones including as many

Reliable Equations of State of Viscous Strong and Electroweak Matter

For the first time, a reliable estimation for the equations of state (EoS), bulk viscosity, and relaxation time, at temperatures ranging from a few MeV up to TeV or energy density up to 10 GeV/fm.

Viscous cosmologies

We probe into universes filled with quark gluon plasma with non-zero viscosities. In particular, we study the evolution of a universe with non-zero shear viscosity motivated by the theoretical result

Quark and strange quark matter in f(R) gravity for Bianchi type I and V space-times

Behaviors of quark matter and strange quark matter which exist in the first seconds of the early Universe in f(R) gravity are studied for Bianchi I and V universes. In this respect, we obtain exact
