Quantum Electrodynamics of Strong Fields: With an Introduction into Modern Relativistic Quantum Mechanics

The fundamental goal of physics is an understanding of the forces of nature in their simplest and most general terms. Yet there is much more involved than just a basic set of equations which eventually has to be solved when applied to specific problems. We have learned in recent years that the structure of the ground state of field theories (with which we are generally concerned) plays an equally fundamental role as the equations of motion themselves. Heisenberg was probably the first to re...
