Hairy AdS black holes with a toroidal horizon in 4D Einstein-nonlinear σ-model system

An exact hairy asymptotically locally AdS black hole solution with a flat horizon in the Einstein-nonlinear sigma model system in (3+1) dimensions is constructed. The ansatz for the nonlinear SU(2) field is regular everywhere and depends explicitly on Killing coordinates, but in such a way that its...
