Graviton propagation in ghost-free massive gravity
Claudia de Rham, Jan Kożuszek, Andrew J. Tolley +1
We consider the ghost-free dRGT massive gravity with two of its three possible mass terms. This theory has five gravitational degrees of freedom. On Minkowski spacetime these modes…
Ill-posedness of the Cauchy problem for linearized gravity in a cavity with conformal boundary conditions
Xiaoyi Liu, Harvey S. Reall, Jorge E. Santos +1
We consider Lorentzian General Relativity in a cavity with a timelike boundary, with conformal boundary conditions and also a generalization of these boundary conditions. We focus…
Towards a uniqueness theorem for static black holes in Kaluza-Klein theory with small circle size
Emma Albertini, Daniel Platt, Toby Wiseman
Kaluza-Klein theory, by which we mean vacuum gravity in 5-dimensions, with asymptotics that are a product of a circle with Minkowski spacetime, has a variety of different static bl…
Well-posedness of minimal dRGT massive gravity
Jan Kożuszek, Toby Wiseman
Ghost-free dRGT massive gravity is a subtle theory, even at the classical level. Its viability depends on Vainshtein screening, which is an intrinsically non-linear phenomenon, and…
Dynamics of dRGT ghost-free massive gravity in spherical symmetry
Emma Albertini, Jan Kożuszek, Toby Wiseman
We focus on dRGT massive gravity in spherical symmetry in the limit of small graviton mass. Firstly we examine the minimal model. This does not exhibit a Vainshtein mechanism in sp…
New Well-Posed Boundary Conditions for Semi-Classical Euclidean Gravity
Xiaoyi Liu, Jorge E. Santos, Toby Wiseman
We consider four-dimensional Euclidean gravity in a finite cavity. Dirichlet conditions do not yield a well-posed elliptic system, and Anderson has suggested boundary conditions th…
From Black Strings to Black Holes
T. Wiseman
Using recently developed numerical methods, we examine neutral compactified non-uniform black strings which connect to the Gregory-Laflamme critical point. By studying the geometry…
Static Axisymmetric Vacuum Solutions and Non-Uniform Black Strings
T. Wiseman
We describe new numerical methods to solve the static axisymmetric vacuum Einstein equations in more than four dimensions. As an illustration, we study the compactified non-uniform…
Strong Brane Gravity and the Radion at Low Energies
T. Wiseman
For the 2-brane Randall-Sundrum model, we calculate the bulk geometry for strong gravity, in the low matter density regime, for slowly varying matter sources. This is relevant for…
