Octupole moments and the non-universality of free-fall in general relativity
Abraham I. Harte, Paul Ramond
Extended bodies in general relativity do not necessarily fall along geodesics, but can be accelerated. These accelerations depend on an object's angular momentum, as well as on its…
Conservative and dissipative sectors in a nonlinear scalar model for the gravitational self-force problem
Francisco M. Blanco, Eanna E. Flanagan, Abraham I. Harte
When considering how self-interaction affects an object's motion, it can be convenient to decompose the self-force into conservative and dissipative pieces. As a toy model for unde…
Nonlinearly self-interacting extended bodies move as test bodies in effective external fields
Abraham I. Harte, Francisco M. Blanco, Eanna E. Flanagan
In electromagnetism, linearized general relativity, and other contexts, previous work has shown that the laws of motion which govern compact, self-interacting bodies can be obtaine…
Gravitational wave memory and its effects on particles and fields
Abraham I. Harte, Thomas B. Mieling, Marius A. Oancea +1
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 analyzes g…
