ADVANCED QUANTUM PHYSICS - 2022/3
Module code: PHY3044
In light of the Covid-19 pandemic the University has revised its courses to incorporate the ‘Hybrid Learning Experience’ in a departure from previous academic years and previously published information. The University has changed the delivery (and in some cases the content) of its programmes. Further information on the general principles of hybrid learning can be found at: Hybrid learning experience | University of Surrey.
We have updated key module information regarding the pattern of assessment and overall student workload to inform student module choices. We are currently working on bringing remaining published information up to date to reflect current practice in time for the start of the academic year 2021/22.
This means that some information within the programme and module catalogue will be subject to change. Current students are invited to contact their Programme Leader or Academic Hive with any questions relating to the information available.
A FHEQ Level 6 course that reviews the basic principles of quantum mechanics, and develops the following more advanced concepts; Dirac notation, operator methods, orbital and spin angular momentum, a detailed solution of the electronic structure of the Hydrogen atom, matrix mechanics, addition of angular momenta, identical particle symmetry, approximation methods such as the variational method and time independent perturbation theory, time dependent perturbation theory, Fermi’s Golden rule and its applications.

The assessment strategy is designed to provide students with the opportunity to demonstrate their ability to recall and apply the postulates and the methods of quantum mechanics to simple systems. The student will understand how to use operator methods to analyse the simple harmonic oscillator, and angular momentum. The student will be able to represent operators as matrices and use standard matrix methods, for example to compute the eigenvalues and expectation values of operators. The student will also be able to go beyond exact solution methods, and apply approximation methods such as perturbation theory, and variational method to simple systems.
Thus, the summative assessment for this module consists of:
· Coursework, which will take about 20 hours of effort, weighted at 30%
· 2.0 hour examination at the end of the semester (70%), with a section A of compulsory questions and a section B with 2 questions chosen from 3. In Part A answer all questions (40 points); In Part B answer two questions out of three (10-points each). If all three questions in Part B are attempted only the best two will be counted.
Formative assessment and feedback
Weekly problem sets are issued during the course, with tutorials scheduled throughout the semester. At least one of these problem sets will be formally marked and handed back to the student with explicit written feedback.
- To develop a detailed understanding of the postulates of quantum mechanics, and operator methods. The principles learned here will be applied to a variety of problems that can be solved analytically. The module goes beyond analytically soluble problems by introducing a variety of approximation methods.

Methods of Teaching / Learning
The learning and teaching strategy is designed to:
Enable students to understand the physics concepts involved in Quantum Mechanics, how to use mathematical tools to find analytical solutions, and to go beyond these analytical solutions using approximation methods.
The learning and teaching methods include:
3 hours of lectures per week x 11 weeks. Problem sets will be issued throughout the course to give practice at problem-solving.
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.
