Graduate Quantum Mechanics

Meeting Time

CHM 6938 will meet Mondays and Wednesdays from 10:45am-12:00pm in NES 104

Grading

Your work will be graded based on homework assignments and one student project.

Some Useful Preliminaries

Partial differential equations, linear algebra, Fourier series

These will be reviewed in the course, but undergraduate calculus is required.

Textbooks

• Quantum Mechanics: A Modern and Concise Introductory Course, Daniel Bes (Springer, 2007 (2nd ed) or 2012 (3rd ed))

Bes gives an excellent survey of the myriad applications of QM, and is detailed enough to provide all the tools and intuition needed to do the math. It does as well as anyone should expect in getting at the whys and hows of the confusion that is quantum, including various manifestations of the measurement problem.

eBook

• McQuarrie (Quantum Chemistry, 2nd ed., Univ. Sci. 2007)

McQuarrie focuses in on molecular electronic structure, providing a chemistry compliment to Bes' physics-oriented book. It covers what we need to understand molecular computations, including spectroscopy, thermochemistry, Hartree-Fock and Slater determinants, molecular orbitals, density-functional theory.

Leung and Marshall have written a solutions manual, Problems and Solutions for McQuarrie's QM, Univ. Sci., 2007.

Both these texts are available at the library, and purchasing them is not required for the course.
