These have states that are, respectively, completely symmetric and completely antisymmetric. Fermions possess half-integer spin values, whereas boson

The reader who is principally interested in the solution of specific problems may wish to omit the next sections and proceed directly to Sect. 6.3 and the subsequ

For this reason, as a preliminary to the next topic — the Coulomb potential — we present here a detailed investigation of angular momentum in relativistic quantum mechanics.

The kinetic energy in these states is negative; the particle moves in the opposite direction to one occupying the usual state of positive energy. Thus, a particle carrying the charge of an elec

https://doi.org/10.1007/978-3-658-22612-1 We begin by recalling the transformation behavior of spinors under passive and active transformations, as was described in Sect. 7.1. We will then address the transformation of the four-potential, and also investigate the transformation of the Dirac Hamiltonian.

This is identical in form to the Klein—Gordon equation. The quantized equation of motion of the string and its generalization to three dimensions provides

Starting from the classical Maxwell equations and a discussion of gauge transformations, the quantization will be carried out in the Coulomb gauge. The principal aim in this chapter is to calculate the propagator for the radiation fiel
