A Non--Supersymmetric Dyonic Extreme Reissner--Nordström Black Hole

Ramzi Khuri, Tomas Ortin

We present a dyonic embedding of the extreme Reissner-Nordström black hole in $N = 4$ and $N = 8$ supergravity that breaks all supersymmetries.

Supersymmetric Black Holes in $N = 8$ Supergravity

Ramzi Khuri, Tomas Ortin

We study the embedding of extreme (multi-) dilaton black hole solutions for the values of the parameter $a = 3, 1, 1/ 3, 0$ in $N = 4$ and $N = 8$ four-dimensional supergravity…

Solution--Generating Transformations and the String Effective Action

Eric Bergshoeff, Bert Janssen, Tomas Ortin

We study exhaustively the solution-generating transformations (dualities) that occur in the context of the low-energy effective action of superstring theory. We first consider targ…
