Non Uniform Black Strings and Critical Dimensions in AdSd
نویسنده
چکیده
We study the equations of black strings in spacetimes of arbitrary dimensions with a negative cosmological constant and construct numerically non uniform black strings solutions. Our results suggest the existence of a localised black hole in asymptotically locally AdS spacetime. We also present evidences for a dependence of the critical dimension on the horizon radius.The critical dimension represents the dimension where the order of the phase transition between uniform and non uniform black string changes. Finally, we argue that both, the regular asymptotically locally AdS solution and AdS black string solutions with a very small horizon radius, present a negative tension. This turns out to be an unexpected feature of the solutions.

New stable phase of non uniform black strings in AdSd
We consider the non uniform AdS black string equations in arbitrary number of dimension in a perturbative approach up to order 2. We restrict the study in order 2 to the backreacting modes, since they provide the first relevant corrections on the thermodynamical quantities of the solutions. Our results suggests the existence of a new stable phase for AdS non uniform black strings, namely long n...
متن کاملNew stable phase of non - uniform charged black strings
Non-uniform black strings coupled to a gauge field are constructed by a perturbative method in a wide range of spacetime dimensions. At the linear order of perturbations, we see that the Gregory-Laflamme instability vanishes at the point where the background solution becomes ther-modynamically stable. The emergence/vanishing of the static mode resembles phase transitions, and in fact we find th...
متن کاملNon-uniform black strings in various dimensions
The nonuniform black strings branch, which emerges from the critical GregoryLaflamme string, is numerically constructed in dimensions 6 ≤ D ≤ 11 and extended into the strongly non-linear regime. All the solutions are more massive and less entropic than the marginal string. We find the asymptotic values of the mass, the entropy and other physical variables in the limit of large horizon deformati...
متن کاملStatic Axisymmetric Vacuum Solutions and Non-Uniform Black Strings
We describe new numerical methods to solve the static axisymmetric vacuum Einstein equations in more than four dimensions. As an illustration, we study the compactified non-uniform black string phase connected to the uniform strings at the Gregory-Laflamme critical point. We compute solutions with a ratio of maximum to minimum horizon radius up to nine. For a fixed compactification radius, the ...
متن کاملA critical dimension in the black-string phase transition
In spacetimes with compact dimensions there exist several black object solutions including the black-hole and the black-string. These solutions may become unstable depending on their relative size and the relevant length scale set by the compact dimensions. The transition between these solutions raises puzzles and addresses fundamental questions such as topology change, uniquenesses and cosmic ...
