Extended-body motion in black hole spacetimes: What is possible?
Abraham I. Harte
Free-fall is only approximately universal in general relativity. Different extended bodies can fall in different ways, depending on their internal dynamics. Nevertheless, certain a…
Semi-Classical Backreaction on Asymptotically Anti-de Sitter Black Holes
Peter Taylor, Cormac Breen
We consider a quantum scalar field on the classical background of an asymptotically anti-de Sitter black hole and the backreaction the field's stress-energy tensor induces on the b…
Energy conditions in general relativity and quantum field theory
Eleni-Alexandra Kontou, Ko Sanders
This review summarizes the current status of the energy conditions in general relativity and quantum field theory. We provide a historical review and a summary of technical results…
Extended-body effects and rocket-free orbital maneuvering
Abraham I. Harte, Michael T. Gaffney
The trajectory of a spherical object which falls freely in a gravitational field is fixed by its initial position and velocity. However, an object which can control its shape can a…
