**Undergraduate Lecture Courses**

- 2016-2017: Theoretical Physics M.Phys Option C6
This course is intended to give an introduction to some aspects of many-particle systems, field theory and related ideas. 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. These applications include the classical mechanics of continuum systems, the quantum mechanics and statistical mechanics of many-particle systems, and some basic aspects of relativistic quantum field theory.

The materials associated with the lecture can be found at:

Questions concerning the lecture, the exercises etc. might be asked using the message board. I highly recommend to make use of this opportunity!

Below you find some notes that address questions that students asked by email or on the message board.

Question concerning Eq. (4.50) of the script by Chalker and Lukas.

Question concerning Eq. (1.72) of the my script ``Elements of Classical Field Theory".

In order to solve the first problem on the third exercise sheet, one has to understand some basics about group theory. A concise summary is provided for instance in

Group theory and Lie algebra primer (by U. Haisch)

Some notes that might be useful to better understand causality in QFT can be found here:

Notes ``He, man. Whatzupp (inside the light-cone)?" (by U. Haisch)

A more detailed derivation of (1.14) and (1.15) of my "Canonical Quantization" script can be found here:

Interested and highly-motivated students might also have a look at the following additional material:

Lectures on symmetries in physics (by A. Pilaftsis)

Lectures on quantum field theory (by U. Haisch)Be warned that the latter two scripts were not written with undergraduate readers in mind and that they cover topics that are (far) off the syllabus.

The script on ``Canonical Quantization" is also available in a slightly extended version:

Extended script ``Canonical Quantization" (by U. Haisch)

It contains brief discussions of the cosmological constant problem and the Casimir effect. Both topics are (strictly speaking) not part of the syllabus.

Some notes that try to answer two questions that surfaced when I discussed causality in QFT can be found here:

Notes ``He, man. Whatzupp (inside the light-cone)?" (by U. Haisch)

**Graduate Lecture Courses**

- Michaelmas 2011: Introduction to Quantum Field Theory
This course deals with modern applications of quantum field

theory with emphasize on the quantization of theories involving

scalar and spinor fields. The materials associated with the lecture

are given below.More material will be provided soon.
