Learning Outcomes

On successful completion of this module students should be able to:

1. Apply the concepts of quantum mechanics in molecules, atoms, nuclei and fundamental particles

2. Define a photon and give examples which illustrate its importance

3. State the de Broglie hypothesis and outline the experimental evidence for it.

4. Interpret the wavefunction and use it to demonstrate the key concepts of quantisation of particles in potential wells.

5. Analyse experimental data in terms of quantisation

6. Demonstrate quantum ideas in the understanding of molecular and condensed matter physics

7. Summarise the basic structure of nuclei

8. Explain the stability or otherwise of nuclei

9. Explain the classification of elementary particles into quarks and leptons


This module introduces the fundamental aspects of quantum physics in the undergraduate physics programme.

Brief description

Quantum mechanics is the most successful physics theory created by mankind. It explains aspects of physics ranging from neutron stars through to sub-nuclear particles such as quarks. The module will introduce the concepts of quantum mechanics and use these to explain phenomena in molecular, atomic, nuclear and subnuclear particle physics.
