چکیده

A gravitating global k-monopole produces a tiny gravitational field outside the core in addition to a solid angular deficit in the k-field theory. As a new feature, the gravitational field can be attractive or repulsive depending on the non-canonical kinetic term. PACS numbers: 11.27.+d, 11.10. Lm Gravitating Global k-monopole 2

Critical phenomena of gravitating monopoles in the spacetime of a global monopole

We present a numerical study of critical phenomena (including the Lue-Weinberg phenomenon) arising for gravitating monopoles in a global monopole spacetime. The equations of this model have been recently studied by Spinelly et al. in a domain of parameter space away from the critical points. PACS numbers: 04.20.Jb, 04.40.Nr, 14.80.Hv Typeset using REVTEX [email protected] Betti.Hartmann@du...

A Self-gravitating Dirac-Born-Infeld Global Monopole

We generalize the field theory of global monopole to Dirac-Born-Infeld(DBI) field and investigate the gravitational property of a DBI global monopole in four-dimensional spherically symmetric spacetime. The coupled equations for the metric and the DBI scalar field are solved asymptotically and numerically. It is found that, just as a canonical global monopole, the gravitational effect of DBI gl...

Self-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...

Gravitating Global Monopoles in Extra Dimensions and the Brane World Concept

Multidimensional configurations with Minkowski external space-time and a spherically symmetric global monopole in extra dimensions are discussed in the context of the brane world concept. The monopole is formed with a hedgehog-like set of scalar fields φi with a symmetry-breaking potential V depending on the magnitude φ2 = φiφi . All possible kinds of globally regular configurations are singled...

Gravitating Dyons and Dyonic Black Holes

We study static spherically symmetric gravitating dyon solutions and dyonic black holes in Einstein-Yang-Mills-Higgs theory. The gravitating dyon solutions share many features with the gravitating monopole solutions. In particular, gravitating dyon solutions and dyonic black holes exist only up to a maximal coupling constant, and beside the fundamental dyon solutions there are excited dyon solu...
