Quark-hadron phase transitions in the viscous early universe [PDF]
Based on hot big bang theory, the cosmological matter is conjectured to undergo QCD phase transition(s) to hadrons, when the universe was about $1-10 μ$s old. In the present work, we study the quark-hadron phase transition, by taking into account the effect of the bulk viscosity.

Phase Transitions and Topological Defects in the Early Universe [PDF]
Our present theories of particle physics and cosmology, taken together, suggest that very early in its history, the universe underwent a series of phase transitions, at which topological defects, similar to those formed in some condensed matter transitions, may have been created.

Braneworld Graviton Interactions in Early Universe Phase Transitions
These are proceedings for the Les Houches Summer School ``Particle Physics and Cosmology: the Fabric of Spacetime,'' held in Les Houches, France, July 31--August 25, 2006. We summarise the discussions of our working group and outline a procedure for calculating gravity corrections to scalar field potentials, as they might be relevant for inflationary ...

Supercooled phase transitions in the very early universe
The universe might have had a prolonged exponentially expanding phase caused by its being stuck in a metastable state of the grand unified phase transition. The only way that it could exit from this exponential expansion without introducing too much inhomogeneity or spatial curvature would be through a homogeneous “bubble” solution in which quantum ...

Quark confinement and phase transition in the early universe
Abstract In the context of the hadronic phase transition in the early universe, the Plumer-Raha-Weiner model for quark confinement is found to limit the bag constant B to the narrow range (170 MeV) 4 –(190 MeV) 4 for an assumed transition temperature of 200 MeV.

Phase transitions and the birth of early universe particle physics
This paper provides a conceptual history of the development of early universe particle physics in the 1970s, focusing on the development of more sophisticated tools for constructing gauge-theories at finite-temperature. I start with a focus on early investigations into spontaneous symmetry restoration, and continue through the development of functional
