Global monopoles, cosmological constant and maximal mass conjecture
Yves Brihaye, Betti Hartmann, Eugen Radu
We consider global monopoles as well as black holes with global monopole hair in Einstein-Goldstone model with a cosmological constant in four spacetime dimensions. Similar to the…
Tachyons on Dp-branes from Abelian Higgs sphalerons
Yves Brihaye, Betti Hartmann
We consider the Abelian Higgs model in a (p+2)-dimensional space time with topology M^{p+1} x S^1 as a field theoretical toy model for tachyon condensation on Dp-branes. The theory…
On cosmological solutions in a spontaneously broken gauge theory
Yves Brihaye, Betti Hartmann, Eugen Radu
We consider solutions of the Yang-Mills-Higgs system coupled to gravity in asymptotically de Sitter spacetime. The basic features of two classes of solutions are discussed, one of…
Black strings in (4+1)-dimensional Einstein-Yang-Mills theory
Y. Brihaye, B. Hartmann, E. Radu
We study two classes of static uniform black string solutions in a (4+1)-dimensional SU(2) Einstein-Yang-Mills model. These configurations possess a regular event horizon and corre…
Exotic composites: the decay of deficit angles in global-local monopoles
Ana Achucarro, Betti Hartmann, Jon Urrestilla
We study static, spherically symmetric, composite global-local monopoles with a direct interaction term between the two sectors in the regime where the interaction potential is lar…
Deformed vortices in (4+1)-dimensional Einstein-Yang-Mills theory
Yves Brihaye, Betti Hartmann, Eugen Radu
We study vortex-type solutions in a (4+1)-dimensional Einstein-Yang-Mills-SU(2) model. Assuming all fields to be independent on the extra coordinate, these solutions correspond in…
