Query: Kinetic Theory and Stochastic Simulation of Field Quanta   We develop quantum electrodynamics into a kinetic-theory-like evolution
equation for electrons, positrons and photons. To keep the "collision rules"
simple, we make use of longitudinal and temporal photons in addition to the
usual transverse photons. For our explicitly time-dependent approach, we
introduce proper time-correlation functions. We then develop a stochastic
simulation technique for solving the resulting kinetic equation and we comment
on the subtleties associated with gauge invariance, Lorentz invariance and
divergent integrals. To illustrate the validity and power of the proposed
ideas, we show how a very simple simulation of the dynamics of field quanta can
be used to obtain the main contribution to the anomalous magnetic moment of the
electron.
