Taking a heuristic approach to relativistic quantum mechanics, Practical
Quantum Electrodynamics provides a complete introduction to the theory,
methodologies, and calculations used for explaining the physical interaction of
This book combines the principles of relativity and quantum theory necessary
for performing the calculations of the electromagnetic scattering of electrons
and positrons and the emission and absorption of photons. Beginning with an
introduction of the wave equations for spin-0 and spin-1/2 particles, the
author compares and contrasts the relativistic and spin effects for both types
of particles. He emphasizes how the relativistic treatment of quantum mechanics
and the spin-1/2 degree of freedom are necessary to describe electromagnetic
interactions involving electron scattering and points out the shortfalls of the
wave-equation approach to relativistic quantum mechanics. Developing the
Feynman rules for quantum electrodynamics by example, the book offers an
intuitive, hands-on approach for performing fundamental calculations. It also
illustrates how to perform calculations that can be related to experiments such
as diagrams, lifetimes, and cross sections.
Practical Quantum Electrodynamics builds a strong foundation for further
studies and research in theoretical and particle physics, particularly
relativistic quantum field theory or nonrelativistic many-body theory.
