This courses deepens the understanding of quantum mechanics by studying important quantum phenomena and applications of quantum mechanics. This comprises the study of indistinguishable quantum particles and their statistical distributions and the use of perturbation methods to understand the level structure of atoms. The details of the observed emission spectrum of hydrogen are inconsistent with the Bohr model and simple analytical solutions of the Schrödinger equation. Most notably, the so called spin-orbit coupling gives rise to small shifts and splittings of the Bohr levels. The coupling of an atom to an external oscillating field gives rise to stimulated emission and can be understood in the framework of time-dependent perturbation theory. The ground state of Helium and simple molecules will be discussed using the variational principle.
After the course the student should be familiar with the following concepts and should be able to apply these concepts to perform simple calculations.
• Quantum statistical description of indistinguishable particles
• Fermi-Dirac, Bose-Einstein and Planck distribution
• Understanding of the strucuture of atoms and periodic table using hydrogen orbitals
• Density of states
• Time-independent perturbation theory
• Fine-structure and hyperfinestructure of Hydrogen
• Influence of external magnetic field (Zeeman-effect) and electrical field (Stark-effect)
• Time-dependent perturbation theory and application to two-level systems
• Stimulated and spontaneous emission, Einstein A and B coefficeints, selection rules
• Variational principle: ground state of Helium and covalent bond
In addition the student is introduced tot he following concept
• Dirac equation
• Adiabatic principle
• Geometrical phase and the Aharonov-Bohm effect
Mode of instruction
Lectures, tutorials (exercise classes) and homework assignments
Total course load 5 EC = 140 hours, of which 42 hours are spent attending lectures and tutorials (11x2 hours lectures + 10x2 hours tutorials). Approximately 40 hoursare needed to study the course material. The remaining 58 hours are spent on completing the assignments and preparing for the exam
Written exam (closed book) with open questions.
The final grade is calculated using the grade of the exam and adding a bonus of maximally 1 point to be earned by handing in homework assignments. For the retake exam the bonus does not apply.
Course material is on blackboard
