Part II.Bookmarks 17 & 18: The electric field accelerates the CM of the particle but doesn’t affect the spin, whereas the magnetic field produces a precession with Larmor angular velocity (as depicted, after one turn the spin points in the opposite direction, the spin needs two complete turns to point in the same direction as originally) .
The figures are modeled in Mathematica with the equations and code provided in the previous post (Part II .17) and bookmarked in the Manipulate plots with the referred numbers (17. and 18.)

In this post we are going to analyze the electron-electron interaction by making use of the Spinning Particle Model, adding the interaction with a second particle and electromagnetic fields.
Since the Poincaré invariant interaction is relativistically invariant it can be used for analyzing high energy scattering processes.
We will show that in the Poincaré invariant description the net binding force that holds linked two Dirac particles is stronger than in the Coulomb case, and it is possible to form a stable spin 1 system of 2 Dirac particles. This bosonic state of spin 1 does not correspond to a Cooper pair because the separation between the centers of mass of the Dirac particles is below Compton’s wavelength, smaller than the correlation distance of the Cooper pair.
