Phys. Rev. D 79, 123525 (2009) [14 pages]Charged seven-dimensional spacetimes with spherically symmetric extra dimensionsReceived 1 April 2009; published 26 June 2009 We derive exact solutions of the seven-dimensional Einstein-Maxwell equations for a spacetime exhibiting Poincaré invariance along four dimensions and spherical symmetry in the extra dimensions. Such topology generically arises in the context of braneworld models. Our solutions generalize previous results on Ricci-flat spacetimes admitting the two-sphere and are shown to include wormhole configurations. A regular coordinate system suitable to describe the whole spacetime is singled out, and we discuss the physical relevance of the derived solutions. © 2009 The American Physical Society URL:
