Vector two-point functions in maximally symmetric spaces

- B. Allen, T. Jacobson
- Mathematics
- 2 June 1986

We obtain massive and massless vector two-point functions in maximally symmetric spaces (and vacua) of any number of dimensions. These include de Sitter space and anti-de Sitter space, and their… Expand

Gravity with a dynamical preferred frame

- T. Jacobson, D. Mattingly
- Physics
- 14 July 2000

We study a generally covariant model in which local Lorentz invariance is broken "spontaneously" by a dynamical unit timelike vector field $u^a$---the "aether". Such a model makes it possible to… Expand

Einstein-aether gravity: a status report

- T. Jacobson
- Physics
- 10 January 2008

This paper reviews the theory, phenomenology, and observational constraints on the coupling parameters of Einstein-aether gravity, i.e. General Relativity coupled to a dynamical unit timelike vector… Expand

Black holes in Einstein-aether and Hořava-Lifshitz gravity

- E. Barausse, T. Jacobson, T. Sotiriou
- Physics
- 14 April 2011

We study spherical black hole solutions in Einstein-aether theory, a Lorentz-violating gravitational theory consisting of general relativity with a dynamical unit timelike vector (the ``aether'')… Expand

Lorentz violation at high energy: Concepts, phenomena, and astrophysical constraints

Extended Horava gravity and Einstein-aether theory

- T. Jacobson
- Physics, Mathematics
- 27 January 2010

Einstein-aether theory is general relativity coupled to a dynamical, unit timelike vector. If this vector is restricted in the action to be hypersurface orthogonal, the theory is identical to the IR… Expand

Einstein-aether waves

- T. Jacobson, D. Mattingly
- Physics
- 3 February 2004

Local Lorentz invariance violation can be realized by introducing extra tensor fields in the action that couple to matter. If the Lorentz violation is rotationally invariant in some frame, then it is… Expand

Introduction to Quantum Fields in Curved Spacetime and the Hawking Effect

- T. Jacobson
- Physics
- 14 August 2003

These notes introduce the subject of quantum field theory in curved spacetime and some of its applications and the questions they raise. Topics include particle creation in time-dependent metrics,… Expand

Self-dual 2-forms and gravity

- R. Capovilla, J. Dell, T. Jacobson, L. Mason
- Physics
- 1991

A Palatini-type formulation of gravity coupled to matter and supergravity is given, in which the gravitational variables are a trio of self-dual 2-forms and an SL(2,C) connection. The action is… Expand
