Quantum Field Theory I: Notes and problems from UofT PHY2403 2018 - Tapa dura

Sinopsis

This is a set of course notes from the Fall 2018, University of Toronto Quantum Field Theorry (PHY2403), taught by Prof. Erich Poppitz.

This course covered:

• Introduction: Energy and distance scales; units and conventions. Uncertainty relations in the relativistic domain and the need for multiple particle description.
• Canonical quantization. Free scalar field theory.
• Symmetries and conservation laws.
• Interacting fields: Feynman diagrams and the S matrix; decay widths and phase space.
• Spin 1/2 fields: Spinor representations, Dirac and Weyl spinors, Dirac equation. Quantizing fermi fields and statistics.
• Vector fields and Quantum electrodynamics.

This book contains:

• Lecture notes.
• Personal notes exploring auxiliary details.
• Worked practice problems. - My solutions (as-is, with errors. ) for problem sets 1-4.
