Nonsingular global strings.
We examine the possibility that time dependence might remove the singular nature of global string spacetimes. We first show that this time dependence takes a specific form – a de-Sitter like expansion along the length of the string and give an argument for the existence of such a solution, estimating the rate of expansion. We compare our solution to the singular Cohen-Kaplan spacetime. PACS num...
متن کاملInflation and Nonsingular Spacetimes of Cosmic Strings
Inflation of cosmic gauge and global strings is investigated by numerically solving the combined Einstein and field equations. Above some critical symmetry-breaking scales, the strings undergo inflation along the radial direction as well as the axial direction at the core. The nonsingular nature of the spacetimes around supercritical gauge and global strings is discussed and contrasted to the s...
متن کاملNonsingular global string compactifications
We consider an exotic "compactification" of spacetime in which there are two infinite extra dimensions, using a global string instead of a domain wall. By having a negative cosmological constant we prove the existence of a nonsingular static solution using a dynamical systems argument. A nonsingular solution also exists in the absence of a cosmological constant with a time-dependent metric. We ...
متن کاملNonsingular static global string
A new solution for the spacetime outside the core of a U (1) static global string has been presented which is nonsingular. This is the first example of a nonsingular spacetime around a static global string. It is believed that early universe has undergone a number of phase transitions as it cooled down from the hot initial phase. One of the immediate consequences of these phase transitions is t...
متن کاملSelf-Gravitating Global Monopole and Nonsingular Cosmology
We review some recent results concerning the properties of a spherically symmetric global monopole in (D = d+2)-dimensional general relativity. Some common features of monopole solutions are found independently of the choice of the symmetry-breaking potential. Thus, the solutions show six types of qualitative behavior and can contain at most one simple horizon. For the standard Mexican hat (Hig...
