【 摘 要 】

Abstract In this article we study a family of four-dimensional, N $$ \mathcal{N} $$ = 2 supergravity theories that interpolates between all the single dilaton truncations of the SO(8) gauged N $$ \mathcal{N} $$ = 8 supergravity. In this infinitely many theories characterized by two real numbers — the interpolation parameter and the dyonic “angle” of the gauging — we construct non-extremal electrically or magnetically charged black hole solutions and their supersymmetric limits. All the supersymmetric black holes have non-singular horizons with spherical, hyperbolic or planar topology. Some of these supersymmetric and non-extremal black holes are new examples in the N $$ \mathcal{N} $$ = 8 theory that do not belong to the STU model. We compute the asymptotic charges, thermodynamics and boundary conditions of these black holes and show that all of them, except one, introduce a triple trace deformation in the dual theory.
