Abstract

In this work, we provide consistent compactifications of Einstein-Maxwell and Einstein-Maxwell-Lovelock theories on direct product spacetimes of the form , where is a Euclidean internal manifold of constant curvature. For these compactifications to take place, the distribution of a precise flux of -forms over the internal manifold is required. The dynamics of the -forms are demanded to be controlled by two types of interactions: first, by specific couplings with the curvature tensor and, second, by a suitable interaction with the electromagnetic field of the -dimensional brane, the latter being dictated by a modification of the recently proposed theory of quasitopological electromagnetism. The field equations of the corresponding compactified theories, which are of second order, are solved, and general homogenously charged black -branes are constructed. We explicitly provide homogenous Reissner-Nordström black strings and black -branes in Einstein-Maxwell theory and homogenously charged Boulware-Deser black -branes for quadratic and cubic Maxwell-Lovelock gravities.
