Why do accelerated charges emits a photon?

[xaratustra]

Can you recommend any literature that supports this approach? That the only electromagnetically accelerated charge emits electromagnetic radiation?

I just got a marvelous book on this very fascinating (and very complicated) issue of classical charged particles within the Maxwell theory. I highly recommend it since it's a very clear exposition of classical electromagnetics and on top solves (at least it claims so) the age-old problem of the selfconsistent dynamics of classical point charges and electromagnetic fields:

Didn't know about his book. He also has a http://www.sciencedirect.com/science/article/pii/S037596010100264X" in which he describes his method. I found some threads in PF and some papers in arXiv. It seems that:

• as long as the particle is not too small, the semi-classical approach can be used. This is called the Abraham-Lorentz-Dirac equation see e.g. http://arxiv.org/abs/gr-qc/9912045" .
• otherwise you should use the QED approach which is called Abraham-Lorentz-Dirac-Lengevin (ALDL) equation.

I was also checking the movement of charge particle in the gravitational field. There are many papers trying to derive equations to determine whether and when the particle does and doesn't radiate. For example http://iopscience.iop.org/0264-9381/21/16/R01". But in none of the sources I could see any hint, that confirms the post #21 and #4 in this thread.

Any ideas?
