Super-Geometrodynamics
M. Cvetic, G. W. Gibbons, C. N. Pope
We present explicit solutions of the time-symmetric initial value constraints, expressed in terms of freely specfiable harmonic functions for examples of supergravity theories, whi…
Conformal Carroll groups
C. Duval, G. W. Gibbons, P. A. Horvathy
Conformal extensions of Levy-Leblond's Carroll group, based on geometric properties analogous to those of Newton-Cartan space-time are proposed. The extensions are labelled by an i…
Killing tensors and canonical geometry
M. Cariglia, G. W. Gibbons, J. -W. van Holten +3
The systematic derivation of constants of the motion, based on Killing tensors and the gauge covariant approach, is outlined. Quantum dots are shown to support second-, third- and…
Separability and Dynamical Symmetry of Quantum Dots
P. -M. Zhang, L. -P. Zou, P. A. Horvathy +1
The separability and Runge-Lenz-type dynamical symmetry of the internal dynamics of certain two-electron Quantum Dots, found by Simonović et al. [1], is traced back to that of the…
Global Structure of Five-dimensional BPS Fuzzballs
G. W. Gibbons, N. P. Warner
We describe and study families of BPS microstate geometries, namely, smooth, horizonless asymptotically-flat solutions to supergravity. We examine these solutions from the perspect…
Anti-de-Sitter spacetime and its uses
G. W. Gibbons
This is a pedagogic account of some of the global properties of Anti-de-Sitter spacetime with a view to their application to the AdS/CFT correspondence. Particular care is taken ov…
Supergravity vacua and solitons
G. W. Gibbons
This is the written version of two lectures given at the Newton Institute Euroconference on Duality and Supersymmetric Theories, Cambridge, England, 7-18 Apr 1997. It deals with th…
Universal Area Product Formulae for Rotating and Charged Black Holes in Four and Higher Dimensions
M. Cvetic, G. W. Gibbons, C. N. Pope
We present explicit results for the product of all horizon areas for general rotating multi-charge black holes, both in asymptotically flat and asymptotically anti-de Sitter spacet…
Deforming the Maxwell-Sim Algebra
G. W. Gibbons, Joaquim Gomis, C. N. Pope
The Maxwell alegbra is a non-central extension of the Poincaré algebra, in which the momentum generators no longer commute, but satisfy . The charges com…
Einstein Metrics on Group Manifolds and Cosets
G. W. Gibbons, H. Lu, C. N. Pope
It is well known that every compact simple group manifold G admits a bi-invariant Einstein metric, invariant under G_L\times G_R. Less well known is that every compact simple group…
The General Supersymmetric Solution of Topologically Massive Supergravity
G. W. Gibbons, C. N. Pope, E. Sezgin
We find the general fully non-linear solution of topologically massive supergravity admitting a Killing spinor. It is of plane-wave type, with a null Killing vector field. Converse…
Metrics With Vanishing Quantum Corrections
A. A. Coley, G. W. Gibbons, S. Hervik +1
We investigate solutions of the classical Einstein or supergravity equations that solve any set of quantum corrected Einstein equations in which the Einstein tensor plus a multiple…
Decay of Massive Dirac Hair on a Brane-World Black Hole
Gary W. Gibbons, Marek Rogatko, Agnieszka Szypłowska
We investigate the intermediate and late-time behaviour of the massive Dirac spinor field in the background of static spherically symmetric brane-world black hole solutions. The in…
The Geometry of Large Causal Diamonds and the No Hair Property of Asymptotically de-Sitter Spacetimes
G. W. Gibbons, S. N. Solodukhin
In a previous paper we obtained formulae for the volume of a causal diamond or Alexandrov open set whose duration is short compared with the curvatur…
Gravitational Solitons and the Squashed Seven-Sphere
P. Bizon, T. Chmaj, G. W. Gibbons +1
We discuss some aspects of higher-dimensional gravitational solitons and kinks, including in particular their stability. We illustrate our discussion with the examples of (non-BPS)…
Hidden symmetry of hyperbolic monopole motion
G. W. Gibbons, C. M. Warnick
Hyperbolic monopole motion is studied for well separated monopoles. It is shown that the motion of a hyperbolic monopole in the presence of one or more fixed monopoles is equivalen…
Partition Functions, the Bekenstein Bound and Temperature Inversion in Anti-de Sitter Space and its Conformal Boundary
G. W. Gibbons, M. J. Perry, C. N. Pope
We reformulate the Bekenstein bound as the requirement of positivity of the Helmholtz free energy at the minimum value of the function L=E- S/(2πR), where R is some measure of the…
Horava-Witten Stability: eppur si muove
W. Chen, Z. -W. Chong, G. W. Gibbons +2
We construct exact time-dependent solutions of the supergravity equations of motion in which two initially non-singular branes, one with positive and the other with negative tensio…
Brane Worlds in Collision
G. W. Gibbons, H. Lu, C. N. Pope
We obtain an exact solution of the supergravity equations of motion in which the four-dimensional observed universe is one of a number of colliding D3-branes in a Calabi-Yau backgr…
The First Law of Thermodynamics for Kerr-Anti-de Sitter Black Holes
G. W. Gibbons, M. J. Perry, C. N. Pope
We obtain expressions for the mass and angular momenta of rotating black holes in anti-de Sitter backgrounds in four, five and higher dimensions. We verify explicitly that our expr…
Separability and Killing Tensors in Kerr-Taub-NUT-de Sitter Metrics in Higher Dimensions
Z. -W. Chong, G. W. Gibbons, H. Lu +1
A generalisation of the four-dimensional Kerr-de Sitter metrics to include a NUT charge is well known, and is included within a class of metrics obtained by Plebanski. In this pape…
Ghost-Free de Sitter Supergravities as Consistent Reductions of String and M-theory
M. Cvetic, G. W. Gibbons, C. N. Pope
We study properties of supergravity theories with non-compact gaugings, and their higher-dimensional interpretations via consistent reductions on the inhomogeneous non-compact hype…
A String and M-theory Origin for the Salam-Sezgin Model
M. Cvetic, G. W. Gibbons, C. N. Pope
An M/string-theory origin for the six-dimensional Salam-Sezgin chiral gauged supergravity is obtained, by embedding it as a consistent Pauli-type reduction of type I or heterotic s…
The Maximum Tension Principle in General Relativity
G W Gibbons
I suggest that classical General Relativity in four spacetime dimensions incorporates a Principal of Maximal Tension and give arguments to show that the value of the maximal tensio…
