A Brownian Particle and Fields II: Radiation Reaction as an Application

Abstract

Radiation reaction has been investigated traditionally in classical dynamics and recently in nonlinear QED as high-intensity field physics produced by high-intensity lasers. Its quantumness is predicted by the factor in the radiation formula. In this Volume II, the quantization of radiation reaction by using a Brownian scalar electron is discussed for obtaining the above radiation formula. Finally, its stochasticity is found as the origin of the factor of its quantumness in high-intensity field physics regime.
