Abstract
After the development of a radiating electron model by P. A. M. Dirac in 1938, many authors have tried to reformulate this model so-called radiation reaction. Recently, this effect has become important in ultra-intense laser-electron (plasma) interactions. In our recent research, we found the stabilization method of radiation reaction by the QED vacuum fluctuation [PTEP 2014, 043A01 (2014), PTEP 2015, 023A01 (2015)]. On the other hand, the modification of the radiated field by highly intense incoming laser fields should be taken into account when the laser intensity is higher than 1022W/cm2, which could be achieved by the next generation ultra-short pulse 10PW lasers, like the ones under construction for the ELI-NP facility. In this paper, I propose the running charge-mass method for the description of the QED-based synchrotron radiation by high-intensity external fields with the stabilization by the QED vacuum fluctuation as an extension to the model by Dirac.
Highlights
With the rapid progress of ultra-short-pulse laser technology, the maximum intensities of these lasers have reached the order of 1022 W/cm2 [1,2]
I succeeded in performing the stabilization of this run-away in the quantum electrodynamics (QED) vacuum fluctuation [8,9,10]
Where τ0 is the constant in Eq (2), τ0 = e2/6π ε0m0c3 = O(10−24 sec), and cτ0 describes the order of the classical electron radius
Summary
With the rapid progress of ultra-short-pulse laser technology, the maximum intensities of these lasers have reached the order of 1022 W/cm2 [1,2]. It is considered that the dynamics of an electron should be corrected in the highly intense fields produced by 10 PW lasers, by QED-based synchrotron radiation. In this physics regime, it is often discussed in terms of the parameter χ ∈ R, representing the field strength [14]: χ. I discuss the general method of the model adaptation from the modified radiation field FMod-LAD in high-intensity external fields (such as laser) to the field propagation in QED vacuum with new degrees of freedom such as the extension from Refs.
