Skyrmion and Skyrme-Black holes in de Sitter spacetime
Y. Brihaye, T. Delsate
Numerical arguments are presented for the existence of regular and black hole solutions of the Einstein-Skyrme equations with a positive cosmological constant. These classical conf…
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…
Dirac oscillators and quasi-exactly solvable operators
Y. Brihaye, A. Nininahazwe
The Dirac equation is considered in the background of potentials of several types, namely scalar and vector-potentials as well as "Dirac-oscillator" potential or some of its genera…
Deformed black strings in 5-dimensional Einstein-Yang-Mills theory
Yves Brihaye, Betti Hartmann
We construct the first examples of deformed non-abelian black strings in a 5-dimensional Einstein-Yang-Mills model. Assuming all fields to be independent of the extra coordinate, w…
