Samlet oversigt over tid og sted for alle kurser inden for Lektionsplan for Det Naturvidenskabelige Fakultet Forår 2013 NAT |
| Undervisnings- periode: |
22. april til 23. juni 2013. |
| Undervisnings- form: |
Lectures and exercises. A large part of the exercises will consist of reading and discussing scientific articles. These articles will describe experiments in quantum optics which realize the effects discussed in the lectures. |
| Formål: |
The course will introduce the students to topics in modern quantum optics, and should bring the student to a level where the students are able to understand the original scientific quantum optics literature. |
| Indhold: |
The course will be an extension on the course “Quantum optics” and will focus on the interaction between light and atoms. The emphasize will be on coherent control of atoms with lasers and on decoherence and methods to control it.
Topics to be covered will probably include:
Coherent effect in atoms: Optical pumping, Ramsay spectroscopy, spin echo, Raman transitions and adiabatic passage.
Description of decoherence. Master equations, Monte Carlo wavefunctions, and Heisenberg-Langevin equations.
Laser cooling
Bose-Einstein condensation. |
| Målbeskrivelse: |
After the course the student should have a thorough understanding of the topics considered in the course and should be able to use the knowledge gained to discuss recent scientific articles in the field.
More specifically the students should be able to
Explain coherent effect in two level systems, such as dressed states, Ramsay spectroscopy, and spin echo.
Discuss the description of decoherence and dissipation in terms of master equations, Monte Carlo wavefunctions, and Heisenberg-Langevin equations. Also the students should be able to relate these concepts to the input-output formalism for optical cavities and be able to explain methods to modify decoherence.
Explain Raman transitions and dark states for multi-level systems.
Explain adiabatic processes such as Landau-Zener and Stirap processes.
Explain both Doppler and sub-Doppler laser cooling
Explain Bose-Einstein condensation (BEC) in dilute atomic gasses and optical lattices as well as the description of BEC in terms of Gross-Pitaevski equations.
Relate the various parts of the course together and apply the knowledge gained in the course in new situations.
Importantly, the student should be able to explain how the effects considered are realized experimentally and give example of this for real quantum optics experiments.
The grade 12 is given to student who clearly demonstrates that the goals are fulfilled with no or only very minor exceptions.
The grade 2 is given for the least acceptable fulfillment of the goal.

| Lærebøger: |
Various notes and articles. |
| Tilmelding: |
Tilmelding foregår på Selvbetjeningen i perioden 15.november - 1. december. |
| Faglige forudsætninger: |
The students should have followed the Quantum optics course or something similar. It is assumed that the students have a good background in quantum mechanics, e.g., through following the physics curriculum for the first three years or similar. Also it may be an advantage if the students have followed a course on Optical Physics and Lasers. |
