Cosmic strings in a space-time with positive cosmological constant
Yves Brihaye, Betti Hartmann
We study Abelian strings in a fixed de Sitter background. We find that the gauge and Higgs fields extend smoothly across the cosmological horizon and that the string solutions have…
Remarks on bell-shaped lumps: stability and fermionic modes
Y. Brihaye, T. Delsate
We consider non-topological, "bell-shaped" localized and regular solutions available in some 1+1 dimensional scalar field theories. Several properties of such solutions are studied…
Five-dimensional rotating black holes in Einstein-Gauss-Bonnet theory
Y. Brihaye, E. Radu
We present arguments for the existence of five-dimensional rotating black holes with equal magnitude angular momenta in Einstein-Gauss-Bonnet theory with negative cosmological cons…
Asymptotic analysis of the Skyrmed monopole
Y. Brihaye, J. Burzlaff, D. H. Tchrakian
We consider a variant of the Georgi Glashow model in the BPS limit, augmented by a higher derivative Skyrme-like term, which is the simplest YMH model that can support monopole bou…
On the stability of AdS black strings
Y. Brihaye, T. Delsate, E. Radu
We explore via linearized perturbation theory the Gregory-Laflamme instability of the black string solutions of Einstein's equations with negative cosmological constant recently di…
Superconducting and Spinning Non-Abelian Flux Tubes
Y. Brihaye, Y. Verbin
We find new non-Abelian flux tube solutions in a model of scalar fields in the fundamental representation of SU(N)xU(1) with (the ``extended non-Abelian Higgs mo…
