Radiation reaction in higher-order electrodynamics

Radiation reaction in 2+1 electrodynamics

A self-action problem for a pointlike charged particle arbitrarily moving in flat spacetime of three dimensions is considered. Outgoing waves carry energy-momentum and angular momentum; the radiation removes energy and angular momentum from the source which then undergoes a radiation reaction. We decompose Noether quantities carried by electromagnetic field into bound and radiative components. ...

On Higher Order Estimates in Quantum Electrodynamics

We propose a new method to derive certain higher order estimates in quantum electrodynamics. Our method is particularly convenient in the application to the non-local semi-relativistic models of quantum electrodynamics as it avoids the use of iterated commutator expansions. We re-derive higher order estimates obtained earlier by Fröhlich, Griesemer, and Schlein and prove new estimates for a non...

Radiation reaction in electrodynamics and the elimination of runaway solutions

The familiar Abraham-Lorentz theory of radiation reaction in classical non-relativistic electrodynamics exhibits many problems such as "runaway solutions" and violation of causality. As shown by many authors, such problems can be alleviated by dropping the assumption of a point electron. We also drop this assumption (by introducing a form-factor with a large cutoff frequency f2) but we present ...

Comment on ‘Self-dressing and radiation reaction in classical electrodynamics’

Using the canonical formalism, Compagno and Persico [J. Phys. A: Math. Gen. 35 (2002) 3629–45] have calculated the ‘radiation-reaction’ force on a uniform spherical charge moving rigidly, slowly and slightly from a point where the transverse electric field is assumed to vanish. This force is shown to result in the same time-averaged self-force as that which has been obtained by different means ...
