PHYS 5093: Group Theory in Quantum Mechanics (Spring 2015, University of Arkansas). 2015 Physics lectures from the University of Arkansas - Fayetteville, AR. These videos are a component of the graduate course PHYS 5093 (502V) - "Group Theory in Quantum Mechanics".

The principle texts are "Quantum Theory in the Computer Age" & "Principles of Symmetry, Dynamics, and Spectroscopy". These were both written by Prof. William G. Harter.

The course utilizes the principles and applications of symmetry analysis to better understand the behavior and spectroscopy of atomic and molecular systems, using symmetry, group representation theory, and Fourier analysis. We attempt to present the mathematical analysis as a consequence of the physical reality, instead of the other way around. This approach helps clarifies the relationship between mathematics and physics, as well as, aids in retention and recall. It is hoped that the techniques and methodologies presented lead to an increased understanding of physics, and illustrate their inherent advantages in computation.
