Phase transitions in the early Universe and their consequences

Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1983
Abstract The reasons for believing that a number of phase transitions occurred in the early Universe are reviewed, and their implications discussed. In particular, the current status of the explanation for the observed values of some constants in terms of the ‘inflationary universe’ is examined.

Phase Transitions in the Early Universe

2001
There are many familiar situations when the properties of some substance change abruptly with temperature T. For example, a liquid may be converted into a vapor or into a solid state. Phase transitions are associated with non-analyticities of the partition function of the system.

NONEQUILIBRIUM PHASE TRANSITIONS IN THE EARLY UNIVERSE

Particles and the Universe, 2004
We review the current issues of nonequilibrium phase transitions, in particular, in the early Universe. Phase transitions cannot maintain thermal equilibrium and become nonequilibrium when the thermal relaxation time scale is bigger than the dynamical time scale.

Effects of phase transitions on the evolution of the early universe

Physical Review D, 1980
In spontaneously broken gauge theories, the gauge symmetry is restored at high temperatures, i.e., in the early universe. As the universe cools, it undergoes a phase transition from the symmetric to asymmetric phase. We examine two interesting cosmological effects of such phase transitions in detail. First, the latent heat released in the SU(2) x U(1)..

Entropy generation and phase transitions in the early universe

Chinese Astronomy and Astrophysics, 1981
Abstract The baryon asymmetry in the universe may have been caused by the B, C, CP non-conserving interactions of the grand unified field theory. In this theory, there must exist spontaneous symmetry breaking which explains the CP nonconservation etc; that is there must have been Higgs phase transations in the early universe. I wish to point out that

Phase Transitions in the Early Universe and Defect Formation

1995
The currently accepted standard models of cosmology and particle physics, taken together, imply that early in its history the Universe underwent a series of symmetry-breaking phase transitions, at which topologically stable defects may have been formed.
