Radiation reaction effects on the interaction of an electron with an intense laser pulse

“…In this order of ideas, considering a charged particle with structure, Ford and O'Connell [25][26][27] by using quantum arguments and a Langevin equation, deduced an equation of motion for the non-relativistic case, known as the Ford equation which can be physically generalized to Special Relativity giving the Eliezer equation [27]. Fourth, within the Shen zone [28] where a classical trajectory can be defined for a charged particle and quantum effects may be neglected, although the Landau-Lifshitz equation and the Eliezer equation are mathematical different, the solutions for both equations are similar and the differences cannot be detected [29][30][31]. Of course, the non-relativistic Landau-Lifshitz equation and the non-relativistic Eliezer equation (Ford equation) [29] are equivalent.…”

The classical central field is analyzed within the Hammond theory of radiation reaction force. For the attractive Coulomb field, the trajectories deduced from Ford and Hammond equations are numerically obtained. Ford and Hammond equations are rewritten by using a recent correction to the non-relativistic equations for charged point particles which include a radiation reaction force term. Also, for the attractive Coulomb case, the trajectories are numerically obtained for both corrected equations. A comparison between all these trajectories is made. It is proved that Hammond equation satisfies the constraint proposed by Dirac of getting an equation of motion which should make the electron in the hydrogen atom spiralling inwards and ultimately falling into the nucleus. A further analysis of the applicability of such a theory is described for experiments particularly in Plasma Physics and some comments are made for the generalization of Hammond equation to General Relativity.

“…Despite worries regarding its perturbative nature, there is evidence to suggest that it is valid provided only that quantum effects can be neglected [13,14]. However, in order to make predictions for experiments under the extreme conditions expected at ELI, it is essential to capture and describe the relevant quantum effects.…”

Next-generation high-power laser facilities (such as the Extreme Light Infrastructure) will provide unprecedented field intensities, and will allow us to probe qualitatively new physical regimes for the first time. One of the important fundamental questions which will be addressed is particle dynamics when radiation reaction and quantum effects play a significant role. Classical theories of radiation reaction predict beam cooling in the interaction of a relativistic electron bunch and a high-intensity laser pulse, with final-state properties only dependent on the laser fluence. The observed quantum suppression of this cooling instead exhibits a dependence on the laser intensity directly. This offers the potential for final-state properties to be modified or even controlled by tailoring the intensity profile of the laser pulse. In addition to beam properties, quantum effects will be manifest in the emitted radiation spectra, which could be manipulated for use as radiation sources. We compare predictions made by classical, quasi-classical and stochastic theories of radiation reaction, and investigate the influence of chirped laser pulses on the observed radiation spectra.
