Abstract

We determine and classify the electric-magnetic duality orbits of fluxes supporting asymptotically flat, extremal black branes in D=4,5,6D=4,5,6 space-time dimensions in the so-called non-supersymmetric magic Maxwell-Einstein theories, which are consistent truncations of maximal supergravity and which can be related to Jordan algebras (and related Freudenthal triple systems) over the split complex numbers Cs\mathbb{C}_{s} and the split quaternions Hs\mathbb{H}_{s}. By studying the stabilizing subalgebras of suitable representatives, realized as bound states of specific weight vectors of the corresponding representation of the electric-magnetic duality symmetry group, we obtain that, as for the case of maximal supergravity, in magic non-supersymmetric Maxwell-Einstein theories there is no splitting of orbits, namely there is only one orbit for each non-maximal rank element of the relevant Jordan algebra (in D=5D=5 and 66) or of the relevant Freudenthal triple system (in D=4D=4).
