Nonsingular global strings.

چکیده

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 numbers: 04.40.-b, 11.10.Lm

Inflation 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...

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 underwent a number of phase transitions as it cooled down from the hot initial phase. One of the immediate consequences of these phase transitions is the f...

A Fast and Accurate Global Maximum Power Point Tracking Method for Solar Strings under Partial Shading Conditions

This paper presents a model-based approach for the global maximum power point (GMPP) tracking of solar strings under partial shading conditions. In the proposed method, the GMPP voltage is estimated without any need to solve numerically the implicit and nonlinear equations of the photovoltaic (PV) string model. In contrast to the existing methods in which first the locations of all the local pe...

Macroscopic open strings and gravitational confinement

We consider classical solutions for strings ending on magnetically charged black holes in four-dimensional Kaluza-Klein theory. We examine the classical superstring and the global vortex, which can be viewed as a nonsingular model for the superstring. We show how both of these can end on a Kaluza-Klein monopole in the absence of self-gravity. Including gravitational back-reaction gives rise to ...

Null cosmological singularities and free strings

We continue exploring free strings in the background of null Kasner-like cosmological singularities, following arXiv:0904.4532 [hep-th]. We study the free string Schrodinger wavefunctional along the lines of arXiv:0807.1517 [hep-th]. We find the wavefunctional to be nonsingular in the vicinity of singularities whose Kasner exponents satisfy certain relations. We compare this with the descriptio...
