Goals:
- Understand the fundamental theories behind modern quantum chemistry computation.
- Can use most quantum chemistry packages to obtained desired information. Know problems that computational quantum chemistry can offer.
Time: Wednesdays 9:10-12:00pm
Place: A508 Institute of Chemistry most of the times.
For the last two lectures: Room 4011 (In the building of Central Office of Administration, 4th floor)
Office hours: Thursdays 10-11 am, by appointment only. Please call or Email.
Grading: 50% Midterm + 50% Homeworks and Quizes
Textbook: [required]
“Modern Quantum Chemistry” by A. Szabo and N. S. Ostlund.
Useful references are: [not required]
- I. N. Levin, Quantum Chemistry
- Mc Quarrie, Quantum Chemistry
- C. J. Cramer, Essentials of Computational Chemistry
- F. Jensen, Introduction to Computational Chemistry
Important policies:
- Homeworks are due one week after they are assigned, before the class starts. Late homeworks and term papers are NOT accepted.
- Discussion when working on homeworks is allowed. However, students are expected to write up their own solutions independently. Identical problem sets will not be graded, and will not receive any credit.

Part II: Jeng, Horng-Tay (鄭弘泰)
Purpose of the course:
This lecture is designed to introduce the modern computational material science based on density functional theory (DFT). This lecture covers theoretical concept and practical applications using first-principles calculations within the local density approximation (LDA). The newly developed LDA+U method which takes the strong correlations U into consideration is also demonstrated to have insight into the localized systems. Also the surface and molecular systems are introduced.
Outline:
- Introduction to CMS and computational package VASP
- Electronic structure calculations of bulk systems
- Electronic structures of transition-metal oxides
- Strong correlations in localized systems
- LDA+U method and applications
- Band decomposed density of states and orbital ordering
- Surface calculations
- Molecular calculations
Evaluation: hands-on + final exam -- 50%
