Mathematical Fundamentals of Quantum Mechanics


Dr Judith A McGovern

Who should take this course?

This course is an alternative to PHYS30101 (Applications of Quantum Mechanics); all students must take one or the other.

There is considerable overlap in material, but the approach in this course will be much more mathematical, and as such it prepares students for future courses in QM and quantum field theory, as well as other course in which QM is used. MPhys students who wants to keep their options open should consider taking this course.

In spite of the title, this is a Physics course with relatively little new mathematics in it after the first three weeks, but an ability to use mathematics confidently is expected. Students who have taken some previous theory courses (advanced dynamics, Lagrangian, complex variables) are more likely to be comfortable with the style of the course. Students who failed to obtain good marks in PHYS20101, PHYS20141 and PHYS2017 (or MT10212) are likely to struggle.

The course starts with directed reading of Chapter 1 of Shankar. following the outline linked below under lectures 1-4. Anyone unsure whether to take this course should start working though these notes; indeed anyone intending to take the course can ease the pressure later by getting started on this.

The course Blackboard site is only used as a repository for some material which cannot be made publically available. Do check it at the start.

Examples Classes

This course will be covered in the examples classes which cover third year core, series "A".

Examples classes will start in week 3. They are not like 1st year workshops, they are more like tutorials for which you do work in advance. It is very important that students work at examples sheets in their own time, and aim to complete the sheets as best they can before the classes. Working together is encouraged!

From week 4 onwards only MFQM sheets need be done in "Quantum" weeks, which alternate with "Particle and Nuclear" weeks after the first class. Solutions will be posted after the Wednesday classes.


Now available as single files: the lecture notes and examples/solutions.


These will be corrected as they are found and listed here (last updated 11th December).


Guidance on the format of the exam (which is unchanged from last year) and on the relevance of questions from the pre-2013/4 exams for PHYS20602 and PHYS30201 is provided here. This includes the formula sheet on the exam. These exams, along with bottom line answers and feedback are available in the Physics UG virtual common room on Blackboard, except for the 2009 bottom-line answers for PHYS20602 which are here. Do make use of the feedback, which indicates common errors made in the past.

Lecture Notes

These lecture notes are from last year, and will be updated as the course progresses (section 1 has already been replaced). They are not expected to change much though.
