The Radiation Reaction Effects in the BMT Model of Spinning Charge and the Radiation Polarization Phenomenon

TL;DR

This paper investigates radiation polarization effects in spinning charges within magnetic fields, using classical self-interaction theory and a semiclassical quantum relation, revealing polarization emergence through natural selection among scattered electrons.

Contribution

It introduces a novel classical approach to explain radiation polarization in spinning charges, linking quantum polarization times with classical self-interaction and natural selection mechanisms.

Findings

Polarization emerges as a result of natural selection among scattered electrons.

The degree of polarization is not complete, indicating partial polarization effects.

Quantum polarization time relates to classical self-interaction parameters.

Abstract

The effect of radiation polarization attended with the motion of spinning charge in the magnetic field could be viewed through the classical theory of self-interaction. The quantum expression for the polarization time follows from the semiclassical relation $T_{QED}\sim \hbar c^{3}/\mu_{B}^2\omega_{c}^3$, and needs quantum explanation neither for the orbit nor for the spin motion. In our approach the polarization emerges as a result of natural selection in the ensenmble of elastically scattered electrons among which the group of particles that bear their spins in the 'right' directions has the smaller probability of radiation. The evidence of non-complete polarization degree is also obtained.
