Module aims

To introduce relativistic quantum field theory, which is the mathematical framework currently used to describe the fundamental interactions of nature (electromagnetism, weak and strong interactions), excluding gravity.

Module learning outcomes

  • Understand the formulation of relativistic field theory.

  • Understand the Dirac equation as the equation for electrons and positrons.

  • Understand how quantum fields give rise to what we see as particles.

  • Have a rough idea about how interactions between particles are described by quantum field theory.

Module content

Syllabus

  • Elementary particles and their interactions (brief survey).

  • Symmetries and conservation laws; Noether’s theorem.

  • Field quantisation and particle interpretation; real or complex scalar fields.

  • The Dirac equation.

  • Quantisation of the Dirac field.

  • Quantisation of the Maxwell field, Interactions.

The information on this page is indicative of the module that is currently on offer. The University is constantly exploring ways to enhance and improve its degree programmes and therefore reserves the right to make variations to the content and method of delivery of modules, and to discontinue modules, if such action is reasonably considered to be necessary by the University. Where appropriate, the University will notify and consult with affected students in advance about any changes that are required in line with the University's policy on the Approval of Modifications to Existing Taught Programmes of Study.
