Precisely Predictable Dirac Observables (Hardcover, 2007 ed.)

This work presents a Clean Quantum Theory of the Electron, based on Dirac's equation. Clean in the sense of a complete mathematical explanation of the well known paradoxes of Dirac's theory, and a connection to classical theory, including the motion of a magnetic moment (spin) in the given field, all for a charged particle (of spin 1/2) moving in a given electromagnetic field. This theory is relativistically covariant, and it may be regarded as a mathematically consistent quantum-mechanical generalization of the classical motion of such a particle, a la Newton and Einstein. Normally, our fields are time-independent, but also discussed is the time-dependent case, where slightly different features prevail. A Schroedinger particle, such as a light quantum, experiences a very different (time-dependent) Precise Predictablity of Observables. An attempt is made to compare both cases.
