Subleading Asymptotic Charges in Massless Scalar QED
Éanna É. Flanagan, Zhihan Liu
We study subleading asymptotic charges of a U(1) gauge field coupled to a charged massless scalar field in Minkowski spacetime. We consider a phase space for which the scalar-field…
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…
Fully nonlinear transformations of the Weyl-Bondi-Metzner-Sachs asymptotic symmetry group
Eanna E. Flanagan, David A. Nichols
The asymptotic symmetry group of general relativity in asymptotically flat spacetimes can be extended from the Bondi-Metzner-Sachs (BMS) group to the generalized BMS (GMBS) group s…
Horizon phase spaces in general relativity
Venkatesa Chandrasekaran, Eanna E. Flanagan
We derive a prescription for the phase space of general relativity on two intersecting null surfaces. The boundary symmetry group is the semidirect product of the group of arbitrar…
Khronometric theories of modified Newtonian dynamics
Eanna E. Flanagan
In 2011 Blanchet and Marsat suggested a fully relativistic version of Milgrom's modified Newtonian dynamics (MOND) in which the dynamical degrees of freedom consist of the spacetim…
