This is a continuation of “Quantum Mechanics of Materials (MAT.A202.R)”, and is the first of a two course sequence with “Quantum Chemistry B (MAT.P202.E)". We begin by reviewing the shortcomings of classical physics and elementary quantum physics. After introducing some useful mathematical tools, we explain the postulates and formulations of quantum mechanics; understanding of operator, physical observable and eigenvalue, commutation relation etc. are developed. The remainder of the course focuses on learning the importance of approximate methods in quantum chemistry and mastering its calculation techniques, such as perturbation and a variation principle. “Quantum Chemistry B (MAT.P202.E)” covers its application to simple real physical systems and is also recommended.
[Outcome] To gain an understanding of advanced materials science, quantum mechanics and the way of its application to chemistry and material engineering are essential in order to answer the questions on the structure and function of materials. Upon successful completion of “Quantum Chemistry A”, students will have accomplished the objectives of learning the approximate methods and techniques in quantum chemistry to apply for real physical systems of materials science and engineering.
[Theme] Quantum mechanics fails to obtain rigorous solutions for complex systems. To overcome these difficulties, many types of approximate methods and techniques have been invented and applied. This course focuses on understanding of perturbation and a variation principle on the basis of elementary quantum mechanics for the application of quantum mechanical calculations.
