MODULE CODEPHY3062 MODULE CONVENERUnknown
DURATION: TERM 1 2 3
DURATION: WEEKS 11
Number of Students Taking Module (anticipated) 46
DESCRIPTION - summary of the module content

The mathematical techniques presented relate directly to the advanced modules at Stages 3 and 4 of Physics programmes, and also have wide applicability across the mathematical sciences. Practical skills are emphasised, rather than formal proofs.

Pre-requisite modules: PHY2025 or equivalent module.

AIMS - intentions of the module

This module aims to develop a deeper understanding of, and greater competence in using, some of the important mathematical methods and techniques of theoretical physics not covered in PHY2025.

INTENDED LEARNING OUTCOMES (ILOs) (see assessment section below for how ILOs will be assessed)
A student who has passed this module should be able to:
 
Module Specific Skills and Knowledge:
1. find a Laurent expansion of a function of a complex variable; identify poles and branch points;
2. evaluate a wide variety of definite integrals using the calculus of residues;
3. use symmetry arguments when evaluating integrals;
4. approximate the value of a definite integral using the method of steepest descent;
5. deduce the first term in Stirling's expansion of the factorial function;
6. approximate the value of the ground-state energy of a bound particle by using the variational method;
7. find approximate solutions of the Shrödinger equation using the WKB method;
8. identify the point group of a simple symmetric object;
9. identify the 'bond', 'site' and continuum problems of percolation theory;
10. solve problems using the theory of conformal mapping;
 
Discipline Specific Skills and Knowledge:
11. apply analytical and numerical skills in mathematics;
12. formulate problems in a logical manner;
13. adapt and apply the methods discussed in lectures to unseen problems;
 
Personal and Key Transferable / Employment Skills and Knowledge:

RE-ASSESSMENT NOTES
An original assessment that is based on both examination and coursework, tests, etc., is considered as a single element for the purpose of referral; i.e., the referred mark is based on the referred examination only, discounting all previous marks. In the event that the mark for a referred assessment is lower than that of the original assessment, the original higher mark will be retained.
 
Physics Modules with PHY Codes
Referred examinations will only be available in PHY3064, PHYM004 and those other modules for which the original assessment includes an examination component - this information is given in individual module descriptors.
