Vacuum Polarization,t is therefore of decisive importance to establish the role played by the effects of conventional radiative QED. Normally, such corrections, in particular vacuum polarization and self-energy (Lamb shift) effects, contribute at most 1% to the particle energies since they are expected to be one power

Vacuum Polarization: Arbitrarily Strong External Potentials, derive the polarization effects for arbitrarily strong potential sources. Clearly, our interest here is directed particularly towards supercritical potentials. Our previously acquired knowledge of the single particle spectrum of the Dirac equation is extensively used and applied throughout this cha

Bosons Bound in Strong Potentials,ed in the following sections differs fundamentally from the conclusions reached for fermions in arbitrarily strong external potentials. It is important to observe here that our intuition, sharpened by experience with classical physics, leads to a reasonably correct picture for bosons, contrary to th

The Hole Theory,charge and positive energy. We discuss the physical successes and shortcomings of this model. The ensuing new kind of symmetry mediating between particles and antiparticles, charge conjugation symmetry, is studied for both free and bound states. In addition the action of parity and time reversal transformations is treated.

The Klein Paradox,a potential barrier of height .. . We first study this paradox purely from the singleparticle stand point to interpret the Dirac equation, i.e. without use of hole theory, as Klein did. Later we introduce the hole-theory interpretation, as was originally done by . .

Resonant States in Supercritical Fields,wer continuum. The energies, widths and wavefunctions of these resonances will be discussed using an analytic description. Also an exact treatment of the Dirac continuum solutions for the Coulomb potential generated by an extended nucleus is presented and the vacuum charge distribution is studied.
