ARES DE PARGA, G.; MARES, R.  and  DOMINGUEZ, S.. An unphysical result for the Landau-Lifshitz equation of motion for a charged particle. Rev. mex. fis. [online]. 2006, vol.52, n.2, pp.139-142. ISSN 0035-001X.

An unphysical result for the Landau-Lifshitz equation of motion for a charged particle is presented. The similarity with the Lorentz-Dirac equation is discussed. Indeed the reaction force obtained for the uniform electric field vanishes when the motion is parallel to it in both cases. A discussion of this unphysical result is given and the need for of an expression for the radiation rate of energy for the Landau-Lifshitz theory is emphasized.

Keywords : Special relativity; classical field theories; radiation reaction force.
