Math 99r: Quantum mechanics for the math-minded

Summer 2021
Instructor: Grant Barkley (firstinital lastname at math.harvard.edu)

An introduction to quantum theory from a mathematical perspective. On the physics side we’ll cover quantum computing, time-dependent and -independent quantum systems, wave-particle duality, harmonic oscillators, quantum algorithms, spin, particle statistics, and path integral formalism. To discuss these formally, we’ll introduce Hilbert spaces, L2 space, unitary and Hermitian operators, functional analysis, the spectral theorem, Fourier transforms, Pontryagin duality, Lie algebras, spin groups, and more. The exact topics covered will depend on the background and interests of the participants.

Prerequisites: Introductory courses in linear algebra and in real analysis. No physics background required.
Lectures: Sundays 8:00pm - 10:00pm ET and Tuesdays/Thursdays 8:30pm - 10:30pm ET, on Zoom
