RELATIVISTIC QUANTUM MECHANICS - 2020/1
Module code: MATM054
In light of the Covid-19 pandemic, and in a departure from previous academic years and previously published information, the University has had to change the delivery (and in some cases the content) of its programmes, together with certain University services and facilities for the academic year 2020/21.
These changes include the implementation of a hybrid teaching approach during 2020/21. Detailed information on all changes is available at: https://www.surrey.ac.uk/coronavirus/course-changes. This webpage sets out information relating to general University changes, and will also direct you to consider additional specific information relating to your chosen programme.
Prior to registering online, you must read this general information and all relevant additional programme specific information. By completing online registration, you acknowledge that you have read such content, and accept all such changes.
This module introduces the basic concepts and techniques of the Quantum Theory of Fields.

Students intending to take the module are encouraged to contact the module coordinator at their earliest convenience for an informal discussion and introduction to the structure of the course, and for possible preliminary reading material if they wish to.
|Assessment type||Unit of assessment||Weighting|
|School-timetabled exam/test||One-hour in-semester test||20|
The assessment strategy is designed to provide students with the opportunity to demonstrate:
Understanding of and ability to interpret and manipulate mathematical statements.
Subject knowledge through the recall of key postulates, theorems and their proofs.
Analytical ability through the solution of unseen problems in the exam and the analysis of slightly more advanced topics in the project.
Thus, the summative assessment for this module consists of:
One two-hour examination (three out of four best answers contribute to the exam mark) at the end of the Semester; worth 80% of the module mark.
One one-hour in-semester test; worth 20% of the module mark.
Formative assessment and feedback
Students receive written feedback via a mid-Semester un-assessed coursework assignment. Students are encouraged to arrange meetings with the module coordinator for questions and verbal feedback on the weekly comprehension of the material throughout the entire duration of the course.
- Introduce students to the mathematical description of relativistic quantum mechanics.
- Enable students to understand the foundations and basic tools of quantum field theory and their applications to the physical world.
- Illustrate standard applications of the theory of quantum fields.

Lecture Hours: 33
Methods of Teaching / Learning
The learning and teaching strategy is designed to provide:
A detailed introduction to the relevant theory and its tenets, and to the appropriate mathematical tools for their implementation
Experience (through demonstration) of the methods used to interpret, understand and solve concrete problems, especially for simple toy-model examples
The learning and teaching methods include:
3 x 1 hour lectures per week x 11 weeks, with black/whiteboard written notes to supplement the module notes and question/answer opportunities for students.
Support during the preparation of the mini group-project report and presentation.
A complete set of self-contained notes will be provided in advance to any topics to be treated.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
