Supersymmetric isolated horizons
Tomas Liko, Ivan Booth
We construct a covariant phase space for rotating weakly isolated horizons in Einstein-Maxwell-Chern-Simons theory in all (odd) dimensions. In particular, we show that hor…
Isolated horizons in higher-dimensional Einstein-Gauss-Bonnet gravity
Tomas Liko, Ivan Booth
The isolated horizon framework was introduced in order to provide a local description of black holes that are in equilibrium with their (possibly dynamic) environment. Over the pas…
Topological deformation of isolated horizons
Tomas Liko
We show that the Gauss-Bonnet term can have physical effects in four dimensions. Specifically, the entropy of a black hole acquires a correction that is proportional to the Euler c…
An exact solution of the five-dimensional Einstein equations with four-dimensional de Sitter-like expansion
Tomas Liko, Paul S. Wesson
We present an exact solution to the Einstein field equations which is Ricci and Riemann flat in five dimensions, but in four dimensions is a good model for the early vacuum-dominat…
The Big Bang as a Phase Transition
Tomas Liko, Paul S. Wesson
We study a five-dimensional cosmological model, which suggests that the universe bagan as a discontinuity in a (Higgs-type) scalar field, or alternatively as a conventional four-di…
