Quantum Theory
A set of online lecture notes intended as an introduction to quantum mechanics and modern atomic physics.

Modern Physics Course
A second year course on special relativity and quantum mechanics. All of the lecture notes can be downloaded, or viewed online.

An Introduction to Relativistic Electronic Structure
A set of lecture notes on quantum chemistry offered at a graduate or advanced undergraduate level. Although written for chemists, there are some useful lessons on relativistic quantum mechanics for physicists as well.

Foundations of Quantum Mechanics
Dirac formalism, harmonic oscillator, multiparticle systems, perturbation expansions, general theory of angular momentum

Wave Particle Duality
A series of pages on the natures of particles and waves and their similarities in the field of modern physics. These pages are intended to aid the reader in the first year Quantum Physics

Advanced Methods in Mathematical Physics
Online note covering the theory of quantum information and quantum computation.

Quantum Mechanics
This is the first part of a Quantum Mechanics class for graduate students. All instructional materials for this class will be distributed electronically over the Internet.

Quantum Mechanics II
This is the second part of a Quantum Mechanics class for graduate students. All instructional materials for this class will be distributed electronically over the Internet.

Physics 511/512 - Advanced Quantum Mechanics
A set of online notes for a graduate level quantum mechanics class.

Theoretical Physics 2
Includes past examination papers, handouts and course synopsis for this course.

An Introduction to Feynman Path Integrals
A short introduction by Christian Grosche to the use of Feynman path integrals in quantum mechanics.

The Solution of Dirac's Equation in Kerr Geometry
A set of online notes by Peggy Varnière on Dirac's equations and their solution in Kerr Geometry.

Three Lectures by Hans Bethe
In 1999, theoretical physicist Hans Bethe delivered three lectures on quantum theory to his neighbors at the Kendal of Ithaca retirement community (near Cornell University). Given by Professor Bethe at age 93, the lectures are presented as QuickTime videos synchronized with slides of his talking points and archival material.
