UE Quantum relativistic mechanics

Degrees incorporating this pedagocial element :

Description

This course is based on the following plan:

A review of Special Relativity and Lorentz transformations.

Relativistic equations 1: spin 0 (Klein-Gordon), spin 1 (Maxwell, covariant electromagnetism), free solution, negative energy and antiparticles.

Relativistic equations 2: spin ½ and Dirac equation, Dirac spinors and matrices. Link with the Lorentz invariance. Electron-photon coupling

Width and cross-section, two-body phase space

Schrödinger, Heisenberg and interaction representations in QM, 

Dyson scattering and expansion matrix, concept of the Feynman diagram

Feynman rules, quantum electrodynamics, photon propagator, Compton cross-section
