A positive energy theorem for Einstein-aether and Hořava gravity
David Garfinkle, Ted Jacobson
Energy positivity is established for a class of solutions to Einstein-aether theory and the IR limit of Hořava gravity within a certain range of coupling parameters. The class cons…
Initial value constraints with tensor matter
Ted Jacobson
In generally covariant metric gravity theories with tensor matter fields, the initial value constraint equations, unlike in general relativity, are in general not just the 0μ-compo…
On horizon structure of bimetric spacetimes
Cédric Deffayet, Ted Jacobson
We discuss the structure of horizons in spacetimes with two metrics, with applications to the Vainshtein mechanism and other examples. We show, without using the field equations, t…
Where is the extremal Kerr ISCO?
Ted Jacobson
Although the circular photon orbit and ISCO for the Kerr black hole remain distinct from each other and from the horizon in the extremal spin limit on a constant Boyer-Lindquist ti…
Membrane paradigm for Einstein-Gauss-Bonnet gravity
Ted Jacobson, Arif Mohd, Sudipta Sarkar
We construct the membrane paradigm for black objects in Einstein-Gauss-Bonnet gravity in spacetime dimensions . As in the case of general relativity, the horizon can be mod…
Hamiltonian structure of Horava gravity
William Donnelly, Ted Jacobson
The Hamiltonian formulation of Horava gravity is derived. In a closed universe the Hamiltonian is a sum of generators of gauge symmetries, the foliation-preserving diffeomorphisms,…
