NFYK14029U Quantum Optics 2
The course will introduce the students to topics in modern quantum optics, and should bring the student to a level where they are able to understand the original scientific quantum optics literature.
The course will be an extension on the course “Quantum optics” and will focus on the interaction between light and atoms. The emphasis will be on coherent control of atoms with lasers and on the theoretical description of 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.
- Coherent effects in two level systems such as dressed states, Ramsay spectroscopy, and spin echo.
- Coherent effects in multilevel systems such as Raman transitions and dark.
- The description of decoherence and dissipation in terms of master equations, Monte Carlo wavefunctions, and Heisenberg-Langevin equations, as well as methods to control decoherence.
- Adiabatic processes
- Doppler and sub-Doppler laser cooling
- How Bose-Einstein condensation (BEC) in dilute atomic gasses are created as well as the theoretical description of BEC in terms of Gross-Pitaevski equations
- Be able to relate the knowledge gained to how these effects are observed in experiments
The course will give the students a background to topics in modern quantum optics, as well as to experimental techniques applied, and thus provides a firm basis for further studies in the field. By working with scientific articles the students will practice reading the original scientific literature.
