Also, revision sessions for C6-AQT students will be held by Prof Parameswaran (week 4) and Prof Starinets (week 6).

Revision class by Prof Parameswaran:

We will have a revision session from 14.00-17.00 on Wednesday, May 19 (Week 4).

The revision will cover 1-2 past papers, as well as address any questions from students.

Aims and Objectives of the Course

This course covers both the C6 (Theory) MPhys option (in MT & HT) and the MMathPhys Advanced Quantum Theory course (in MT only). The course is intended to give an introduction to some aspects of classical and quantum field theory, many-body systems and related issues. It also serves as an introduction to the path integral technique. These form the basis of our current theoretical understanding of particle physics, condensed matter and statistical physics. An aim is to present some core ideas and important applications in a unified way. The applications include classical mechanics of continuum systems, quantum mechanics and statistical mechanics of many-particle systems, and some basic aspects of relativistic quantum field theory.
