Phase Transitions in the Early and Present Universe [PDF]
▪ Abstract The evolution of the universe is the ultimate laboratory for studying fundamental physics across energy scales that span approximately 25 orders of magnitude. The standard models of cosmology and particle physics provide the basic understanding of the early and present universe and predict a series of phase transitions that occurred in ...

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 $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.

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 ...

Reconstructing early universe evolution with gravitational waves from supercooled phase transitions
We study gravitational waves from supercooled cosmological first-order phase transitions. If such a transition is followed by inefficient reheating, the evolution history of the universe is modified by a period of early matter domination.

Generic features of vacuum phase transitions in the early universe
Abstract A simple Higgs model is utilized to show the occurrence of a four-phase pattern of vacuum symmetry. As temperature changes, an interplay of spontaneous symmetry breaking and spontaneous symmetry restoration ensues, and resonant field interchange occurs.

Have pulsar timing arrays detected the hot big bang: Gravitational waves from strong first order phase transitions in the early Universe [PDF]
The origins of matter and radiation in the universe lie in a Hot Big Bang. We present a number of well-motivated cosmologies in which the Big Bang occurs through a strong first order phase transition – either at the end of inflation, after a period of ...

Thermal suppression of bubble nucleation at first-order phase transitions in the early Universe [PDF]
One of the key observables in a gravitational wave power spectrum from a first order phase transition in the early Universe is the mean bubble spacing, which depends on the rate of nucleation of bubbles of the stable phase, as well as the bubble wall ...
