Topological 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 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.
متن کاملTopological Defects in Cosmology 1
Topological defects are ubiquitous in condensed–matter physics but only hypothetical in the early universe. In spite of this, even an indirect evidence for one of these cosmic objects would revolutionize our vision of the cosmos. We give here an introduction to the subject of cosmic topological defects and their possible observable signatures. Beginning with a review of the basics of general de...
متن کاملTopological defects in spherical nematics.
We study the organization of topological defects in a system of nematogens confined to the two-dimensional sphere (S2). We first perform Monte Carlo simulations of a fluid system of hard rods (spherocylinders) living in the tangent plane of S2. The sphere is adiabatically compressed until we reach a jammed nematic state with maximum packing density. The nematic state exhibits four +1/2 disclina...
