Relativität, Teilchen und Felder

What it is about

You learn the foundations of special relativity and the field theory from the Lagrangian density to quantization. In the end you can quantize free and interacting fields, derive Feynman diagrams and rules, and calculate simple cross sections and decay rates.

What you will be able to do

• Understand principles of special relativity
• Apply the principle of least action and Noether's theorem in field theory
• Derive field equations and conserved quantities from a Lagrangian density
• Quantize free scalar, Dirac, and electromagnetic fields
• Quantize interacting field systems
• Draw Feynman diagrams and derive Feynman rules
• Calculate cross sections and decay rates in simple processes (Yukawa theory, QED)

What the module consists of

• VorlesungPresentation of topical content, illustrating universal concepts and integration into scientific discourse
• ÜbungDeepening and practice of the content with problems and example calculations; promotion of autonomous application

Teaching method

• themenorientierte Vorlesungshows content with cross-references between topics and promotes analytical-physical thinking
• Übungsaufgaben in Einzel- und Gruppenarbeitserves to deepen and practically exercise calculation and understanding tasks
• wissenschaftliche Diskussioneninvolves students and fosters their own thinking abilities
