New Taub-NUT-Reissner-Nordström spaces in higher dimensions
Robert B. Mann, Cristian Stelea
We construct new charged solutions of the Einstein-Maxwell field equations with cosmological constant. These solutions describe the nut-charged generalisation of the higher dimensi…
Ghost Condensation in the Brane-World
Robert B. Mann, John J. Oh
Motivated by the ghost condensate model, we study the Randall-Sundrum (RS) brane-world with an arbitrary function of the higher derivative kinetic terms, , where $X…
Entropic N-bound and Maximal Mass Conjecture Violations in Four Dimensional Taub-Bolt(NUT)-dS Spacetimes
R. Clarkson, A. M. Ghezelbash, R. B. Mann
We show that the class of four-dimensional Taub-Bolt(NUT) spacetimes with positive cosmological constant for some values of NUT charges are stable and have entropies that are great…
Nutty Bubbles
A. M. Ghezelbash, R. B. Mann
We investigate the various time-dependent bubble spacetimes that can be obtained from double analytic continuation of asymptotically locally flat/AdS spacetimes with NUT charge. We…
Action, Mass and Entropy of Schwarzschild-de Sitter black holes and the de Sitter/CFT Correspondence
A. M. Ghezelbash, R. B. Mann
We investigate a recent proposal for defining a conserved mass in asymptotically de Sitter spacetimes that is based on a conjectured holographic duality between such spacetimes and…
Abelian Higgs Hair for Rotating and Charged Black Holes
A. M. Ghezelbash, R. B. Mann
We study the problem of vortex solutions in the background of rotating black holes in both asymptotically flat and asymptoticlly anti de Sitter spacetimes. We demonstrate the Abeli…
