This advanced third year physics course provides an introduction to the concepts and tools of quantum field theory (QFT) and to its applications in various fields, such as particle physics and condensed matter. QFT is arguably the most far-reaching attempt to combine special relativity and quantum physics in a unique framework. This course builds on the content of previous courses on Classical and Quantum Mechanics, Electromagnetism, and Statistical Physics, providing an elegant synthesis of these key areas of modern Physics. We explain in this course the origin of particles (why are all electrons identical?), forces (why same charge repel while gravitation is attractive?) and antiparticles. The Feynman path integral formalism is used, leading to Klein-Gordon, Maxwell and Dirac equations. Feynman diagrams to describe interacting fields are also introduced. The concepts of Gauge Invariance, spontaneous symmetry breaking, as well as the Goldstone and Higgs mechanisms are introduced in a general context, and applied, e.g., to describe superfluidity, superconductivity and ferromagnetism.

Learning Outcomes

Upon successful completion, students will have the knowledge and skills to:

  1. Describe the reasons for the failure of relativistic quantum mechanics, such as the causality problem, and the need for quantum field theory
  2. Describe the origin of particles and forces
  3. Analyse the statistical distributions of identical particles and the repulsive/attractive nature of the forces as a function of spins
  4. Apply Feynman rules to calculate probabilities for basic processes with particles (decay and scattering)
  5. Obtain classical and/or non-relativistic limits of fully quantum and relativistic models, and identify the relativistic origin of effects such as the spin-orbit interaction
  6. Use effective field theory techniques to develop models at large scales
  7. Describe qualitatively effects such as superconductivity, superfluidity, and ferromagnetism using the concepts of gauge invariance, Goldstone and Higgs mechanism, and spontaneous symmetry breaking.
  8. Apply mathematical tools such as complex analysis, Gaussian path integration, and Fourier analysis in the context of physical systems
  9. Develop computational skills by solving numerically simple problems such as pionless effective field theory and the Ising model.
  10. Develop oral and written communication skills

Indicative Assessment

  1. Assignments and online questions (50) [LO 1,2,3,4,5,6,7,8,9,10]
  2. Final written exam (50) [LO 1,2,3,4,5,6,7,8]

In response to COVID-19, ANU has changed the mode of delivery for all classes in Semester 1 2020 to remote delivery.

Semester 1 Class Summary information (available under the Classes tab) on this publication is as up to date as possible. Changes to Class Summaries not captured by this publication will be available via Wattle and students should have been advised by the offering College. Find out more information on the University's response to COVID-19 here.

The ANU uses Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. While the use of Turnitin is not mandatory, the ANU highly recommends Turnitin is used by both teaching staff and students. For additional information regarding Turnitin please visit the ANU Online website.

Workload

The expected workload will consist of approximately 130 hours throughout the semester including:

  • Face-to face component which will consist of 1 x 3 hour workshop per week.
  • Approximately 94 hours of self-study which will include listening/viewing the online lectures, preparation for the weekly online lectures, workshops/labs and other assessment tasks.


This is a flipped class.
