In General
> s.a. electromagnetism; classical particles;
particle effects; QED.
* Radiation reaction: The effect
on a radiation-emitting particle due to the fact that energy, momentum and
angular momentum are carried away by the radiation; It can be described in terms
of a "self-force" (Newton's third law does not hold for an accelerated
charge), and is associated with "radiation damping."
* Abraham-Lorentz formula:
An equation giving the non-relativistic form of the self-force arising from
radiation reaction,
Fself = −(4U/3c2) dv/dt + (2e2/3c2) d2v/dt2 + O(a) ,
where a is the particle's radius, and U the electrostatic
self-energy (which blows up as a → 0); It is useful in describing
the motion of radiating electric charges, but it suffers from two notorious
defects, runaway solutions and preacceleration.
* Lorentz-Dirac equation / force:
The fully relativistic, covariant, renormalized form (in c = 1 units) is
m dua / dt = Fexta + (2/3)q2 (δab + uaub) d2ub / dt2 ,
where m includes the "electromagnetic mass" me
= 4U/3c2; > s.a. mass.
* Eliezer's theorem:
An electron moving radially according to the Lorentz-Dirac equation in the
Coulomb field of a proton will not be attracted to a collision with the proton;
Instead, it is repelled from the proton with proper acceleration increasing
asymptotically with proper time; Proponents of the Lorentz-Dirac equation
sometimes try to explain this away by speculation that the electron must
approach so closely to the proton that the field strength would be beyond
the domain of validity of the classical Lorentz-Dirac equation and therefore
require a quantum-mechanical analysis, but this explanation does not seem to hold.
* Issue: The presence
of daa / dt
= d2ua
/ dt2 in the equations introduces considerable
difficulties in their interpretation as equations of motion.
* Runaway, preaccelerated
solutions: If Fext =
0, a solution is v = v0
+ v1 exp{t/τ}, where
τ:= 2e2/3mc2;
The response is that Fself applies
only when Fext ≠ 0 and the energy
loss is small; Confirmed by QED.
* In other dimensions:
(Gal'tsov) Radiation reaction allows a consistent mass renormalization
only in 4D; In odd dimensions Huygens's principle does not hold and
the radiation reaction force depends on the whole past history of the
charge (radiative tail), with a divergence in the tail integral that
can be removed by mass renormalization only in 2+1 dimensions; In even
D > 4, divergences cannot be removed by the mass renormalization
