Students are given an overview of quantum chemistry for the fundamentals of physical chemistry, and provided with the quantum-chemical basics for an idea on materials, from atoms and molecules to molecular aggregates.
Students will understand the principle of the indistinguishability of identical particles, which forms the foundation of physicochemical properties of materials, as well as Pauli's principle, which is derived from it. Students learn about the electronic state (energy band structure), optical and thermodynamic properties of molecular solids. Furthermore, based on statistical mechanics of molecular aggregates, students study the electronic state and electronic properties of molecular aggregates, and learn the concepts of metals, semiconductors, etc.
By the end of this course students will understand
1) the indistinguishability of identical particles and the Pauli principle
2) the hierarchy of energy in molecules and the corresponding spectroscopy
3) the electronic and optical properties of condensed matters and the behavior of metals and semiconductors based on the concept of energy band structure.
