Quantum Field Theory
a cyclist tour notes
Relax by reading Classics Illustrated, diagrammatic, Predragian
vision of field theory.
The exposition assumes no prior knowledge of anything (other
than Taylor expansion of an exponential, taking derivatives,
and inate knack for doodling).
The techniques covered apply to QFT, Stat Mech and stochastic processes.
Feynman's Formulation of Quantum Field Theory
QM Amplitudes as a Sum over Paths
Path integrals, and all that jazz.
Schwinger/Feynman Formulation of Field Theory
Peskin: Sect 7.2 - LSZ reduction, 7.4 Ward-Takahashi indentities
6.A.1: QED Ward identity
Non-Abelian Gauge Invariance
The notes are
preliminary and in constant flux; it is probably wisest to
first browse a chapter of possible interest with a previewer,
before deciding to print anything.
