TLDR
In this article, the sequence of phase transitions during the hot history of the universe is followed within a phenomenological framework, with particular emphasis on the QCD confinement transition, which is at reach under earth laboratory conditions.Abstract:
The sequence of phase transitions during the hot history of the universe is followed within a phenomenological framework. Particular emphasis is put on the QCD confinement transition, which is at reach under earth laboratory conditions. A tepid inflationary scenario on the GUT scale with bubble growth at moderate supercooling is discussed.read more

Nucleation and growth in one dimension. I. The generalized Kolmogorov-Johnson-Mehl-Avrami model
TL;DR: This work generalizes previous work to the case where the nucleation rate is an arbitrary function I (t) and obtains analytical results for the time-dependent distributions of various quantities (such as the island distribution).

The cosmological QCD phase transition revisited
TL;DR: The cosmological implications of such a QCD phase transition in the early universe were explored in this article, where it was shown that the large baryon-asymmetry is diluted by a little inflation where the universe is trapped in a false vacuum state of QCD.

Modifications by the QCD transition and e + e - annihilation of the analytic spectrum of relic gravitational waves in the accelerating universe
TL;DR: In this article, the effects of the QCD transition and the annihilation of the quarks into the massive hadrons were analyzed for a spatially flat universe, evolving from the inflation up to the current acceleration and the spectrum of RGWs was obtained, covering the whole range of frequency.

Improved calculation of relic gravitational waves
TL;DR: In this paper, the authors improved the calculation of the relic gravitational wave (RGW) in two aspects: first, they investigated the transfer function by taking into consideration the redshift-suppression effect, accelerating expansion effect, the damping effect of free-streaming relativistic particles, and the cosmic phase transition, and gave a simple approximate analytic expression.
