Rotating Black Holes in Gauged Supergravities; Thermodynamics, Supersymmetric Limits, Topological Solitons and Time Machines
M. Cvetic, G. W. Gibbons, H. Lu +1
We study the thermodynamics of the recently-discovered non-extremal charged rotating black holes of gauged supergravities in five, seven and four dimensions, obtaining energies, an…
Phantom Matter and the Cosmological Constant
G. W. Gibbons
Motivated by some recent speculative attempts to model the dark energy, scalar fields with negative kinetic energy coupled to gravity without a cosmological constant are considered…
De Sitter Space from Warped Supergravity Solutions
G. W. Gibbons, C. M. Hull
The solutions of 10 and 11 dimensional supergravity that are warped products of de Sitter space with a non-compact `internal' space are investigated. A convenient form of the metri…
Embedding Branes in Flat Two-time Spaces
L. Andrianopoli, M. Derix, G. W. Gibbons +3
We show how non-near horizon, non-dilatonic -brane theories can be obtained from two embedding constraints in a flat higher dimensional space with 2 time directions. In particul…
Wrapping Branes in Space and Time
G W Gibbons
Branes may be approximated semi-classically by solutions of supergravity theories with event and Cauchy horizons. I suggest that if one wishes to avoid singularities and to capture…
Quantum Gravity/String/M-theory/ as we approach the 3rd Millennium
G W Gibbons
I review some recent progress in String/M-theory
