New Black Hole Solutions in N=2 and N=8 Gauged Supergravity

Abstract

We present a N = 2 supergravity model that interpolates between all the single dilaton truncations of the gauged SO(8), N = 8 supergravity. We provide new explicit non-extremal charged black hole solutions and their supersymmetric limits, exploiting the non-trivial transformation of the Fayet-Iliopoulos parameters under electromagnetic duality to connect the electric and the magnetic configurations. We also provide the asymptotic charges, thermodynamics and boundary conditions of these black hole configurations. We then construct a new supersymmetric truncation of the maximal supergravity, this new sector featuring non-extremal and supersymmetric black holes.

Supersymmetric solitons in gauged $\mathcal{N}=8$ supergravity

“…We believe this is a generic feature of such boundary conditions; we intend to provide a general proof in a forthcoming paper. It is also possible to construct black holes in this theory [15][16][17][18][19][20][21] and endow them with Wilson lines along the lines of [22]. This will provide an even more complete phase diagram of this model that we leave to analyze in the future.…”
