Integrability of the Einstein-nonlinear -model in a nontrivial topological sector
Andronikos Paliathanasis, Tim Taves, P. G. L. Leach
The integrability of the\ Einstein-nonlinear -model with nonvanishing cosmological charge is studied. We apply the method of singularity analysis of differential equ…
Cosmological Einstein-Skyrme solutions with non-vanishing topological charge
Fabrizio Canfora, Andronikos Paliathanasis, Tim Taves +1
Time-dependent analytic solutions of the Einstein-Skyrme system --gravitating Skyrmions--, with topological charge one are analyzed in detail. In particular, the question of whethe…
Designer black holes from new 2D gravity
Gabor Kunstatter, Hideki Maeda, Tim Taves
We present a family of extensions of spherically symmetric Einstein-Lanczos-Lovelock gravity. The field equations are second order and obey a generalized Birkhoff's theorem. The Ha…
New 2D dilaton gravity for nonsingular black holes
Gabor Kunstatter, Hideki Maeda, Tim Taves
We construct a two-dimensional action that is an extension of spherically symmetric Einstein-Lanczos-Lovelock gravity. The action contains arbitrary functions of the areal radius a…
Black Hole Formation in Lovelock Gravity
Tim Taves
We first derive the Hamiltonian for Lovelock gravity and find that it takes the same form as in general relativity when written in terms of the Misner-Sharp mass function. We then…
Modelling the Evaporation of Non-singular Black Holes
Tim Taves, Gabor Kunstatter
We present a model for studying the formation and evaporation of non-singular (quantum corrected) black holes. The model is based on a generalized form of the dimensionally reduced…
Hamiltonian dynamics of Lovelock black holes with spherical symmetry
Gabor Kunstatter, Hideki Maeda, Tim Taves
We consider spherically symmetric black holes in generic Lovelock gravity. Using geometrodynamical variables we do a complete Hamiltonian analysis, including derivation of the supe…
Geometrodynamics of spherically symmetric Lovelock gravity
Gabor Kunstatter, Tim Taves, Hideki Maeda
We derive the Hamiltonian for spherically symmetric Lovelock gravity using the geometrodynamics approach pioneered by Kuchař in the context of four-dimensional general relativity.…
Hamiltonian Formulation of Scalar Field Collapse in Einstein Gauss Bonnet Gravity
T. Taves, C. D. Leonard, G. Kunstatter +1
We compute the Hamiltonian for spherically symmetric scalar field collapse in Einstein-Gauss-Bonnet gravity in D dimensions using slicings that are regular across future horizons.…
Higher Dimensional Choptuik Scaling in Painleve Gullstrand Coordinates
Tim Taves, Gabor Kunstatter
We investigate Choptuik scaling in the spherically symmetric collapse of a massless scalar field in higher dimensions using Painleve-Gullstrand (P-G) coordinates. Our analysis conf…
