Defect formation in the early universe

چکیده

Topological defects are common in many everyday systems. In general, they appear if a symmetry is broken at a rapid phase transition. In this article, I explain why it is believed that they should have also been formed in the early universe and how that would have happened. If topological defects are found, this will provide a way to study observationally the first fractions of a second after the Big Bang, but their apparent absence can also tell us many things about the early universe.

Defect Induced Structure Formation in the Early Universe

When describing the early universe as an FRW metric and being filled with perfect fluids, there is no first principle understanding of structure formation. Instead, at high temperatures one must describe the matter as a quantum field theory. As the universe expands, this field theory will undergo phase transitions, and the possibility for topological defects arise. This paper will discuss how t...

Defect Formation and Critical Dynamics in the Early Universe

We study the nonequilibrium dynamics leading to the formation of topological defects in a symmetry-breaking phase transition of a quantum scalar field with λΦ4 self-interaction in a spatially flat, radiation-dominated FriedmannRobertson Walker Universe. The quantum field is initially in a finitetemperature symmetry-restored state and the phase transition develops as the Universe expands and coo...

Critical Slowing down and Defect Formation

The formation of topological defects in a second order phase transition in the early universe is an out-of-equilibrium process. Condensed matter experiments seem to support Zurek’s mechanism, in which the freezing of thermal fluctuations close to the critical point (critical slowing down) plays a crucial role. We discuss how this picture can be extrapolated to the early universe, pointing out t...

What is the future of causal models of cosmic structure formation ? ∗

Recent research has severely constrained the standard “defect” models of cosmic structure formation. Here I discuss the nature of the problems with defect models, and place this discussion in the context of the big picture of cosmic structure formation. In particular, I classify models of cosmic structure formation as either “causal” or “acausal”, and ask whether the problems with the defect mo...

Testing cosmological defect formation in the laboratory

Topological defects such as cosmic strings may have been formed at early-universe phase transitions. Direct tests of this idea are impossible, but the mechanism can be elucidated by studying analogous processes in low-temperature condensed-matter systems. Experiments on vortex formation in superfluid helium and in supercon-ductors have so far yielded somewhat confusing results. I shall discuss ...
