Angaben zur Abhaltung 

This course tracks loosely the German language course of the same name and focuses on Quantum Mechanics, the Physics of Atoms and Molecules and their Interaction with Electromagnetic Fields. Notably, we will review the "machinery" of Quantum Mechanics before discussing the application of the theory to the Hydrogen Atom. We will then move on to explore the interaction of EM fields with the Hatom before moving on to discuss other "oneelectron" atoms, such as the alkali atoms. We will then move on to explore the quantum mechanics of angular momentum before turning our attention to Helium and exchange symmetries. The interactions between quantised magnetic moments (spins) in atoms will then be discussed and we will explore how they interact to produce fine and hyperfine effects int he energy spectrum of atoms. Our discussion of atoms will be completed by a discussion of the action of external electric (Stark effect) and magnetic (Zeeman effect) fields on atoms. Given time at the end of the semester, we will study basic quantum optics of atoms in the context of fewlevel lasers and introduce a couple of modern themes in the study of ultracold quantum gases of atoms. The final topic will concern the physics of molecules, including the formation of chemical bonds to form molecules and their rotational, vibrational and optical properties.

Study of Physics to 4th Semester level. This includes EMtheory, Classical Mechanics, Optics as well as Linear Algebra. 


Upon completion of this course the student will be in a position to :
 Apply quantum mechanics to describe the electronic structure of oneelectron atoms in the English language
 Understand the properties of the Hatom and be analyse the hierarchy of energy scales (coarse, fine and hyperfine structure)
 Understand the concept of spin and be able to apply their understanding to evaluate the energy scale of finestructure interactions.
 Apply QM to calculate the major interactions in the physics of twoelectron atoms.
 Understand the concept of direct and exchange Coulomb interactions.
 Understand and apply how angular mementum Coupling Schemes in MultiElectron Atoms give rise to finestructure and hyperfine structure in the optical spectrum of fewelectron atoms.
 Understand how atoms behave in eternal DC Magnetic Fields (Zeeman effect) and DC Electric Fields (DC Stark Effect)
 Understand the origin of the radiative coupling of electronic states in atoms to light and apply QM to calculate the transition rates, factors influencing radiative line widths.
 Understand the origin of optical selection rules caused by electric dipole, quadrupole and magneticdipole absorption.
 Understand the origin of Einstein Coefficients, Radiative Rate Equations and Solve them to understand the need for Spontaneous and Stimulated Emission.
 Be aware of coherent phenomena such as Rabi Oscillations, Ramsey Interferometry and the AC Stark Effect.
 Understand the operation of MASERs and LASERs and the conditions required to have stimulated emission dominate.
