Sequences of extremal radially excited rotating black holes    [PDF]

Jose Luis Blazquez-Salcedo, Jutta Kunz, Francisco Navarro-Lerida, Eugen Radu
In Einstein-Maxwell-Chern-Simons theory the extremal Reissner-Nordstr\"om solution is no longer the single extremal solution with vanishing angular momentum, when the Chern-Simons coupling constant reaches a critical value. Instead a whole sequence of rotating extremal J=0 solutions arises, labeled by the node number of the magnetic U(1) potential. Associated with the same near horizon solution, the mass of these radially excited extremal solutions converges to the mass of the extremal Reissner-Nordstr\"om solution. On the other hand, not all near horizon solutions are also realized as global solutions
