After some introductory remarks about the prospects of first order phase transitions in the early universe, we discuss in some detail the electroweak phase transition. In the standard model case a clear picture is arising including perturbative and nonperturbative effects. Since in this case the ...
I explore the theory and computation of early-Universe finite-temperature phase transitions involving scalar fields. I focus primarily on the electroweak phase transition, but some of the methods I develop are applicable to any scalar-field cosmological phase transition (such as the computation of the...

Extremely long transition times can result in this case. The conditions for this are given. For the MIT bag model no substantial super-cooling is found to occur in the thin interface approximation. 展开 关键词: Early Universe: Phase Transitions ...
Early Universe: BaryogenesisEarly Universe: Phase TransitionsThe author presents an introduction to the electroweak phase transition. Starting from the dimensional reduction of an equilibrium finite temperature quantum field theory the electroweak phase transition is described by the reduction of the four-...
Cosmological phase transitions in the early universe lead to gradients in the vacuum expectation value of the Higgs field. The variation of the Higgs field results in the presence of electromagnetic fields after the completion of the phase transition. This mechanism would also produce magnetic fields...
At very early times in the universe history a number of phase transformations occurred which led to a large variety of relics such as: density and gravitational waves, topologically stable extended objects (monopolies, strings, domain walls, etc...), lumps of strange matter and, possibly, more...
