This lecture is intended for students of the Master's studies or IPSP programme in Physics. Basic knowledge in quantum mechanics and relativistic physics will be required.

Aims

Students comprehend the basic terms, phenomena and concepts of atomic and molecular physics. After active participation in the module, they are able to analyze and independently solve tasks from these areas. They can apply the acquired knowledge to typical experiments and transfer them to new problems. They are able to work with terms of atomic and molecular physics and to present and justify their solutions to problems in these areas.
