Quantum Mechanics and Modeling I

Wave function of an excited electron trapped in a cubic box: a model for a quantum dot state

- Introduction to basic concepts in quantum physics and their relationship to chemistry, modern materials science, and the engineering of nanodevices.
- To achieve the goals of this course, a mathematically rigorous approach is combined with a physical interpretation of the concepts, and the application of the most important quantum mechanical models to electronic and magnetic spectroscopies and chemistry is illustrated.

Hourly volumes*:

            CM (Readings):24 hours

            TD (Tutorials): 12 hours

By the end of the course, students should be able to:

• A real understanding of the quantum nature of matter; an introduction to simple models in quantum mechanics.
• a true understanding of the theoretical formalism used to describe quantum phenomena, which is necessary for the characterization and engineering of materials.
• in-depth knowledge of electronic states; quantum numbers, electronic transitions, and their relationship to spectroscopy; electronic states in electric and magnetic fields.
• the necessary background for further study of computational modeling methods and advanced techniques applicable to the elucidation of electronic and geometric structures, as well as the spectroscopic properties of materials.
