Gravitational self force and gauge transformations
We explore how the gravitational self force (or “radiation reaction” force), acting on a pointlike test particle in curved spacetime, is modified in a gauge transformation. We derive the general transformation law, describing the change in the self force in terms of the infinitesimal displacement vector associated with the gauge transformation. Based on this transformation law, we extend the re...
متن کاملGauge problem in the gravitational self-force: Harmonic gauge approach in the Schwarzschild background
The metric perturbation induced by a particle in the Schwarzschild background is usually calculated in the Regge-Wheeler ~RW! gauge, whereas the gravitational self-force is known to be given by the tail part of the metric perturbation in the harmonic gauge. Thus, to identify the gravitational self-force correctly in a specified gauge, it is necessary to find out a gauge transformation that conn...

متن کاملPerspective on gravitational self-force analyses
A point particle of mass μ moving on a geodesic creates a perturbation hab, of the spacetime metric gab, that diverges at the particle. Simple expressions are given for the singular μ/r part of hab and its tidal distortion caused by the spacetime. This singular part hab is described in different coordinate systems and in different gauges. Subtracting hab from hab leaves a regular remainder hab....
متن کامل5 Perspective on gravitational self - force analyses .
A point particle of mass μ moving on a geodesic creates a perturbation hab, of the spacetime metric gab, that diverges at the particle. Simple expressions are given for the singular μ/r part of hab and its distortion caused by the spacetime. This singular part hS ab is described in different coordinate systems and in different gauges. Subtracting hS ab from hab leaves a regular remainder h R ab...
