**Quantum Electrodynamics Based on Self-Fields** - Jonathan Dowling

In an extension of the neoclassical theory of Jaynes, which itself an
independent rediscovery of an old idea by Fermi, we will discuss the
Self-Field Electrodynamics of Barut and show how this semiclassical
theory can be used to recover such QED effects as spontaneous
emission, Lamb shift, and g-2, all without field second quantization.
We will also discuss how the Jaynes neoclassical theory was limited
by the two-level approximation, which is removed in the Barut theory.
The self-field theory agrees with full QED in all cases computed so
far, up to first order in the fine structure expansion.
