Advanced Quantum Chemistry by Patrik R. Callis
This note is concerned with the application of quantum mechanics to many-electron systems like atoms and molecules. Stationary as well as time-dependent states have been covered, emphasizing in particular electronic and vibrational states. The following topics have been dealt with: the necessity of quantum mechanics, properties of the wavefunction, kinetic energy, tunneling, and the variation principle. It includes applications of symmetry and group theory in quantum mechanics and incorporates them with the Schrödinger equation. It also includes time-dependent quantum chemistry-including propagation of density matrices and time evolution of probability distributions. The target of the note is aimed at those who seek to understand the complexities of many-body systems in quantum chemistry.
