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…
Nonabelian solutions in a Melvin magnetic universe
Burkhard Kleihaus, Jutta Kunz, Eugen Radu
We show the existence of D=4 nonabelian solutions approaching asymptotically a dilatonic Melvin spacetime background. An exact solution generalizing the Chamseddine-Volkov soliton…
Spherically symmetric selfdual Yang-Mills instantons on curved backgrounds in all even dimensions
Eugen Radu, D. H. Tchrakian, Yisong Yang
We present several different classes of selfdual Yang-Mills instantons in all even d backgrounds with Euclidean signature. In d=4p+2 the only solutions we found are on constant cur…
AdS rotating non-Abelian black holes
Y. Brihaye, E. Radu, D. H. Tchrakian
We present arguments for the existence of charged, rotating black holes with equal magnitude angular momenta in Einstein-Yang-Mills theory with negative cosmological constant…
Magnetic solutions in AdS and trace anomalies
Y. Brihaye, E. Radu
We discuss black hole and black string solutions in d=5 Einstein-Yang-Mills theory with negative cosmological constant, proposing a method to compute their mass and action. The mag…
Goldstone models in D+1 dimensions, D=3,4,5, supporting stable and zero topological charge solutions
Eugen Radu, D. H. Tchrakian
We study finite energy static solutions to a global symmetry breaking Goldstone model described by an isovector scalar field in D+1 spacetime dimensions. Both topologically stable…
