[HTML][HTML] Quasi-local energy-momentum and angular momentum in general relativity

LB Szabados - Living reviews in relativity, 2009 - Springer
The present status of the quasi-local mass, energy-momentum and angular-momentum
constructions in general relativity is reviewed. First, the general ideas, concepts, and …

Matching post-Newtonian and numerical relativity waveforms: Systematic errors and a new phenomenological model for nonprecessing black hole binaries

L Santamaria, F Ohme, P Ajith, B Brügmann… - Physical Review D …, 2010 - APS
We present a new phenomenological gravitational waveform model for the inspiral and
coalescence of nonprecessing spinning black hole binaries. Our approach is based on a …

Persistent gravitational wave observables: general framework

ÉÉ Flanagan, AM Grant, AI Harte, DA Nichols - Physical Review D, 2019 - APS
The gravitational wave memory effect is characterized by the permanent relative
displacement of a pair of initially comoving test particles that is caused by the passage of a …

Spin Hall effects and the localization of massless spinning particles

AI Harte, MA Oancea - Physical Review D, 2022 - APS
The spin Hall effects of light represent a diverse class of polarization-dependent physical
phenomena involving the dynamics of electromagnetic wave packets. In a medium with an …

Gravitational wave memory and its effects on particles and fields

AI Harte, TB Mieling, MA Oancea… - arXiv preprint arXiv …, 2024 - arxiv.org
Gravitational wave memory is said to arise when a gravitational wave burst produces
changes in a physical system that persist even after that wave has passed. This paper …

Mechanics of extended masses in general relativity

AI Harte - Classical and quantum gravity, 2012 - iopscience.iop.org
Abstract The'external'or'bulk'motion of extended bodies is studied in general relativity.
Compact material objects of essentially arbitrary shape, spin, internal composition and …

Motion in classical field theories and the foundations of the self-force problem

AI Harte - Equations of Motion in Relativistic Gravity, 2015 - Springer
This article serves as a pedagogical introduction to the problem of motion in classical field
theories. The primary focus is on self-interaction: How does an object's own field affect its …

Local symmetries as constraints on the motion of freely falling extended bodies

AI Harte, D Dwyer - Physical Review D, 2023 - APS
Different extended objects can fall in different ways, depending on their internal structures.
Some motions are nevertheless impossible, regardless of internal structure. This paper …

Caustics and wave propagation in curved spacetimes

AI Harte, TD Drivas - Physical Review D—Particles, Fields, Gravitation, and …, 2012 - APS
We investigate the effects of light cone caustics on the propagation of linear scalar fields in
generic four-dimensional spacetimes. In particular, we analyze the singular structure of …

Self-forces from generalized Killing fields

AI Harte - Classical and Quantum Gravity, 2008 - iopscience.iop.org
A non-perturbative formalism is developed that simplifies the understanding of self-forces
and self-torques acting on extended scalar charges in curved spacetimes. Laws of motion …
