non-BPS Attractors, Fixed Scalars and Magic Supergravities

We analyze the Hessian matrix of the black hole potential of N = 8, d = 4 supergravity, and determine its rank at non-BPS critical points, relating the resulting spectrum to non-BPS solutions (with non-vanishing central charge) of N = 2, d = 4 magic supergravities and their “mirror” duals. We find agreement with the known degeneracy splitting of N = 2 non-BPS spectrum of generic special Kähler ...

Abstract Recently it has been observed that the group E7 can be used to describe a special type of quantum entanglement of seven qubits partitioned into seven tripartite systems. Here we show that this curious type of entanglement is entirely encoded into the discrete geometry of the Fano plane. We explicitly work out the details concerning a qubit interpretation of the E7 generators as represe...

We derive and solve the black hole attractor conditions of N = 8 supergravity by finding the critical points of the corresponding black hole potential. This is achieved by a simple generalization of the symplectic structure of the special geometry to all extended supergravities with N > 2. There are two classes of solutions for regular black holes, one for 1/8 BPS ones and one for the non-BPS. ...

Ghost - Free de Sitter Supergravities as Consistent Reductions of String and M - theory

We study properties of supergravity theories with non-compact gaugings, and their higher-dimensional interpretations via consistent reductions on the inhomogeneous non-compact hyperboloidal spaces H p,q. The gauged supergravities are free of ghosts, despite the non-compactness of the gauge groups. We give a general discussion of the existence of stationary points in the scalar potentials of suc...

Domain - wall Supergravities from Sphere Reduction

Kaluza-Klein sphere reductions of supergravities that admit AdS×Sphere vacuum solutions are believed to be consistent. The examples include the S4 and S7 reductions of eleven-dimensional supergravity, and the S5 reduction of ten-dimensional type IIB supergravity. In this paper we provide evidence that sphere reductions of supergravities that admit instead Domain-wall×Sphere vacuum solutions are...
