During the past century, there has been considerable discussion and analysis of the motion
of a point charge in an external electromagnetic field in special relativity, taking into account …

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 …

We derive an expression for the second-order gravitational self-force that acts on a self-
gravitating compact object moving in a curved background spacetime. First we develop a …

Various regularization methods have been used to compute the self-force acting on a static
particle in a static, curved spacetime. Many of these are based on Hadamard's two-point …

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 …

We study the dynamics of acomposite'ordressed'quark in strongly-coupled large-N c Script
N= 4 super-Yang-Mills, making use of the AdS/CFT correspondence. We show that the …

We calculate the electrostatic self-force on an electric dipole in the spacetime generated by
a static, thin, infinite and straight cosmic string. The electric dipole is held fixed in different …

The Abraham–Lorentz force is a finite remnant of the UV singular structure of the self-
interaction of a point charge with its own field. The satisfactory description of such an …

We discuss the solution proposed by Fermi to the so called “4/3 problem” in the classical
theory of the electron, a problem which puzzled the physics community for many decades …

Building upon previous results in scalar field theory, a formalism is developed that uses
generalized Killing fields to understand the behavior of extended charges interacting with …
