A scalar field instability of rotating and charged black holes in (4+1)-dimensional Anti-de Sitter space-time
Y. Brihaye, B. Hartmann
We study the stability of static as well as of rotating and charged black holes in (4+1)-dimensional Anti-de Sitter space-time which possess spherical horizon topology. We observe…
Stability of superconducting strings coupled to cosmic strings
Alexandru Babeanu, Betti Hartmann
We study the stability of superconducting strings in a U(1)_{local} x U(1)_{global} model coupled via a gauge field interaction term to U(1) Abelian-Higgs strings. The effect of th…
Stability of Gauss-Bonnet black holes in Anti-de-Sitter space-time against scalar field condensation
Yves Brihaye, Betti Hartmann
We study the stability of static, hyperbolic Gauss-Bonnet black holes in (4+1)-dimensional Anti-de-Sitter (AdS) space-time against the formation of scalar hair. Close to extremalit…
Particle motion in Horava-Lifshitz black hole space-times
Victor Enolskii, Betti Hartmann, Valeria Kagramanova +3
We study the particle motion in the space-time of a Kehagias-Sfetsos (KS) black hole. This is a static spherically symmetric solution of a Horava-Lifshitz gravity model that reduce…
Hyperelliptic integrals and Hořava-Lifshitz black hole space-times
Victor Enolski, Betti Hartmann, Valeria Kagramanova +3
The description of many dynamical problems like the particle motion in higher dimensional spherically and axially symmetric space-times is reduced to the inversion of hyperelliptic…
Holographic superfluid/fluid/insulator phase transitions in 2+1 dimensions
Yves Brihaye, Betti Hartmann
We study the breaking of an Abelian symmetry close to the horizon of a black string as well as close to the tip of a solitonic, cigar-shaped solution in (3+1)-dimensional Anti-de S…
