Non-Supersymmetric Attractors in Symmetric Coset Spaces

Understand

We present a method of constructing generic single-centered and multi-centered extremal black hole solutions in a large class of 4D N=2 supergravities coupled to vector-multiplets with cubic prepotentials.

• The method is applicable to models for which the 3D moduli spaces obtained via c*-map are symmetric coset spaces.
• The attractor solutions are generated by certain nilpotent elements in the coset algebra.
• We present explicit computations in 4D N=2 supergravity coupled to one vector-multiplet, whose 3D moduli space is the symmetric coset space G_{2(2)}/SL(2,R)^2.
