Sequences of extremal radially excited rotating black holes — Jose Luis Blazquez-Salcedo1, •Jutta Kunz2, Francisco Navarro-Lerida1, and Eugen Radu2 — 1Universidad Complutense de Madrid — 2Universität Oldenburg
In 5-dimensional Einstein-Maxwell-Chern-Simons theory with Chern-Simons coefficient λ the solutions are only known in closed form, when λ=1. For λ ≠ 1 the charged rotating black hole solutions are obtained numerically. Beyond λ=1 counterrotating black holes appear. Moreover, for λ>2 uniqueness is lost. Here the extremal Reissner-Nordström solution is no longer the single extremal solution with vanishing angular momentum. Instead a whole sequence of rotating extremal J=0 solutions arises, which can be labeled by the node number of the magnetic U(1) potential. These global black hole solutions thus represent a sequence of radially excited extremal solutions. They are associated with the same near horizon solution, and their mass converges to the mass of the extremal Reissner-Nordström solution. On the other hand, not all near horizon solutions are also realized as global solutions.
