Graduate Quantum Mechanics

Text Syllabus

Meeting Time

CHM 6938-005 (Quantum Mechanics I) will meet Mondays and Wednesdays from 10:45am-12:00pm in NES 104.

The instructor may be reached anytime by phone 4-4298 or email (username: davidrogers on usf.edu).

Course Overview & Objectives

Nanoscience has already reached its natural quantum limit, bringing the 'spooky' behavior of quantum systems into the center of a revolution. This course will rigorously develop the fundamentals of quantum mechanics required for understanding the interplay of electricity and magnetism with electronic structure.

By the end of the course, you will be able to determine which problems in chemistry and physics have an essentially quantum nature. For those that do, you will know the rules for formulating the solution mathematically and the tools and special tricks for completing the solution. You will also learn aspects of numerical solutions and partial differential equations that apply to many aspect of modern technology outside of QM. As a research course, you will be expected to finish with a high-level understanding of where to find worked projects similar to new and open questions, and to mix, match, and evaluate solution techniques before diving into differentiation or trial and error.

Grading & Due Dates

Your work will be graded based on homework assignments (80%) and one student project (20%).

Homework 1: Monday, September 16 Homework 2: TBA

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 (possibly in course reserves), and purchasing them is not required for the course.
