Constraints and gauge transformations: Dirac's theorem is not always valid
Julian Barbour, Brendan Z. Foster
A standard tenet of canonical quantum gravity is that evolution generated by a Hamiltonian constraint is just a gauge transformation on the phase space and therefore does not chang…
Strong field effects on binary systems in Einstein-aether theory
Brendan Z. Foster
"Einstein-aether" theory is a generally covariant theory of gravity containing a dynamical preferred frame. This article continues an examination of effects on the motion of binary…
Noether charges and black hole mechanics in Einstein-aether theory
Brendan Z. Foster
The Noether charge method for defining the Hamiltonian of a diffeomorphism-invariant field theory is applied to "Einstein-aether" theory, in which gravity couples to a dynamical, t…
Post-Newtonian parameters and constraints on Einstein-aether theory
Brendan Z. Foster, Ted Jacobson
We analyze the observational and theoretical constraints on ``Einstein-aether theory", a generally covariant theory of gravity coupled to a dynamical, unit, timelike vector field t…
Metric Redefinitions in Einstein-Aether Theory
Brendan Z. Foster
`Einstein-Aether' theory, in which gravity couples to a dynamical, time-like, unit-norm vector field, provides a means for studying Lorentz violation in a generally covariant setti…
A first-principles derivation of York scaling and the Lichnerowicz-York equation
Edward Anderson, Julian Barbour, Brendan Z. Foster +2
The only efficient and robust method of generating consistent initial data in general relativity is the conformal technique initiated by Lichnerowicz and perfected by York. In the…
