Higuchi, A. and Giles, M.D.R. (2004) Lorentz-Dirac force from QED for linear acceleration. Physical Review D, 70 (8/0817). pp. 1-5. ISSN 1550-2368
We investigate the motion of a wave packet of a charged scalar particle linearly accelerated by a static potential in quantum electrodynamics. We calculate the expectation value of the position of the charged particle after the acceleration to first order in the fine structure constant in the ℏ→0 limit. We find that the change in the expectation value of the position (the position shift) due to radiation reaction agrees exactly with the result obtained using the Lorentz-Dirac force in classical electrodynamics. We also point out that the one-loop correction to the potential may contribute to the position change in this limit.
