Self-forces from generalized Killing fields

Harte, Abraham I.

Understand

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 are locally derived using momenta generated by a set of generalized Killing fields.
  • Self-interactions that may be interpreted as arising from the details of a body's internal structure are shown to have very simple geometric and physical interpretations.
  • Certain modifications to the usual definition for a center-of-mass are identified that significantly simplify the motions of charges with strong self-fields.
