David Tong: Supersymmetric Quantum Mechanics

David Tong: Lectures on Supersymmetric Quantum Mechanics

These are introductory lectures on supersymmetric quantum mechanics, aimed at Masters students. They describe some applications of quantum mechanics to ideas in geometry.

The lecture notes are around 100 pages. Please do email me if you find any typos or mistakes.
