Timetable:
Lectures and problem sessions (werkcolleges) are mixed, on most Tuesdays at 9:00 - 10:45 and Thursdays 13:30 - 15:15 in room H226. There are exceptions so please check below for possible room and time changes. The problem sessions are interactive. The material covered in the problems constitutes an essential part of the programme.Office hours: to be determined directly with the students
Date | Contents (tentative - make sure to check again later). Version updated on December 10 |
7/9, 12/9, 14/9 | Introduction: effective field theories, classical and quantum. Relativistic (classical) field theory. Lagrangian formulation. An important example: the electromagnetic field. Gauge potential. Scalar fields (real, complex). (T 1.1). A first look at perturbations, scaling and renormalization. Mass dimension of fields and coupling constants. Relevant, marginal and irrelevant terms in the Effective lagrangian at low energies. |
