David Tong: The Quantum Hall Effect

David Tong: Lectures on the Quantum Hall Effect

This is a course on the quantum Hall effect, given in TIFR, Mumbai. The first four chapters require only basic quantum mechanics; the final two chapters need techniques from quantum field theory. The full lecture notes are around 230 pages. They are also available to download at the arXiv. Please do email me if you find any typos or mistakes.
