This course provides an introduction to quantum field theory as one of the cornerstones of modern physics, and how it inevitably emerges from combining quantum mechanics with special relativity. The focus is on how to quantize both bosonic and fermionic fields, and how a relatively small number of fundamental symmetry principles leads to the construction of the standard model of particle physics.
Relativistic quantum mechanics was developed and extended into quantum electrodynamics (qed), which is the relativistic quantum field theory of electrodynamics describing mathematically all phenomena involving electrically charged particles (in agreement with quantum mechanics and special relativity) that interact by means of exchange of photons, and representing the quantum counterpart of classical electromagnetism by giving a complete account of matter and light interaction.

Dr strickland is a professor of physics at kent state university. His primary interest is the physics of the quark-gluon plasma (qgp) and high-temperature quantum field theory (qft).
