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...
متن کاملProtostar formation in the early universe.
The nature of the first generation of stars in the universe remains largely unknown. Observations imply the existence of massive primordial stars early in the history of the universe, and the standard theory for the growth of cosmic structure predicts that structures grow hierarchically through gravitational instability. We have developed an ab initio computer simulation of the formation of pri...
متن کاملDefect formation in the early universe
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 t...
متن کاملPattern Formation in the Early Universe
Systems that exhibit pattern formation are typically driven and dissipative. In the early universe, parametric resonance can drive explosive particle production called preheating. The fields that are populated then decay quantum mechanically if their particles are unstable. Thus, during preheating, a driven-dissipative system exists. We have shown previously that pattern formation can occur in ...
متن کاملSimulations of Structure Formation in the Universe
Cosmic structure has formed as a result of gravitational amplification of primordial density fluctuations together with the action of other physical processes (adiabatic gas dynamics, radiative cooling, photoionization and recombination, radiative transfer). These complex nonlinear processes, acting over a wide range of length scales (from kiloparsecs to tens of megaparsecs), make this a diffic...
