Requisites

Prerequisite

Aims

To develop the basic concepts of quantum mechanics and apply them to a variety of physical systems.

Overview

Applications of Quantum Physics

Learning outcomes

On completion successful students will be able to:

  1. calculate the probability of tunnelling through a barrier,
  2. solve simple eigenvalue problems for trapped particles,
  3. solve eigenvalue problems for two-state systems,
  4. add angular momenta in quantum mechanics and calculate the fine-structure of atomic energy levels,
  5. calculate first-order shifts in energy levels produced by external fields,
  6. define entangled states in quantum mechanics and use these to describe simple ideas of quantum information.
