Horizon surface gravity as 2d geodesic expansion
Ted Jacobson, Renaud Parentani
The surface gravity of any Killing horizon, in any spacetime dimension, can be interpreted as a local, two-dimensional expansion rate seen by freely falling observers when they cro…
When is g_{tt} g_{rr} = -1?
Ted Jacobson
The Schwarzschild metric, its Reissner-Nordstrom-de Sitter generalizations to higher dimensions, and some further generalizations all share the feature that g_{tt} g_{rr}=-1 in Sch…
Numerical simulations of gravitational collapse in Einstein-aether theory
David Garfinkle, Christopher Eling, Ted Jacobson
We study gravitational collapse of a spherically symmetric scalar field in Einstein-aether theory (general relativity coupled to a dynamical unit timelike vector field). The initia…
Introduction to Quantum Fields in Curved Spacetime and the Hawking Effect
Ted Jacobson
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-de…
Comments on ``Improved limit on quantum-spacetime modifications of Lorentz symmetry from observations of gamma-ray blazars"
T. Jacobson, S. Liberati, D. Mattingly
We address several criticisms by Amelino-Camelia of our recent analyses of two observational constraints on Lorentz violation at order E/M_{Planck}. In particular, we emphasize the…
Black Hole Thermodynamics Today
Ted Jacobson
A brief survey of the major themes and developments of black hole thermodynamics in the 1990's is given, followed by summaries of the talks on this subject at MG8 together with a b…
