Topological Defects and Cosmology
Many particle physics models of matter admit solutions corresponding to stable or long-lived topological defects. In the context of standard cosmology it is then unavoidable that such defects will form during phase transitions in the very early Universe. Certain types of defects lead to disastrous consequences for cosmology, others may play a useful role, as possible seeds for the formation of ...
متن کاملTopological Defects in Cosmology
Topological Defects like magnetic monopoles, cosmic strings, domain walls, etc., could have formed during symmetry breaking phase transitions in the early universe. We give an overview of the implications of topological defects for cosmology, with particular emphasis on their possible role as sources of the extremely high energy cosmic rays detected in several recent cosmic ray experiments; the...
متن کاملTopological Defects in SUSY
Topological defects are general consequences of almost all symmetry breaking processes. They arise naturally when a system goes through a phase transition from a symmetric phase to a phase in which the symmetry is broken. The formation and the evolution of cosmic topological defects in the early (or late) Universe has many direct and observable consequences that may allow us to constrain possib...
متن کاملSemilocal Topological Defects
Semilocal defects are those formed in field theories with spontaneously broken symmetries, where the vacuum manifold M is fibred by the action of the gauge group in a non-trivial way. Studied in this paper is the simplest such class of theories, in which M ≃ S2N−1, fibred by the action of a local U(1) symmetry. Despite M having trivial homotopy groups up to π2N−2, this theory exhibits a fascina...
متن کاملTopological Defects in Cosmology*
The scenario of a cosmology with topological defects is surveyed starting from the field theoretic aspects and ending with a description of large-scale structure formation and magnetic field generation. * Lectures delivered at ICTP, Trieste, July 1993.
