b.    Specific learning outcomes of the teaching unit
At the end of this teaching unit, the student will be able to:
1.      describe the laser-atom interaction with Hamiltonian and density matrix formalisms ;
2.      describe the essential steps leading to atom trapping, cooling and condensation ;
3.      determine the experimental parameters for Doppler and sub-Doppler cooling ;
4.      describe the essential steps leading to nuclear magnetic resonance imaging ;
5.      give a quantum definition of scattering and master the concept of cross section.
 
Content
Laser-atom interactions : two-state model – Rabi oscillations, adiabatic rapid passage, Bloch vector, Ramsey fringes, saturated absorption, and three-state model – optical pumping, two-photon spectroscopy, STIRAP, induced electromagnetic transparency, slow light. Cold atoms, atomic traps and Bose-Einstein condensates : Doppler and sub-Doppler cooling, magneto-optical and dipole trap, evaporative cooling, statistical mechanics of boson condensation, condensate properties, atom lasers. Applications of cold atoms to metrology : atomic clocks, atomic fountains, cold ions in Lamb-Dicke regime, quantum jumps, atomic qubits. Density matrix and Von Neumann-Liouville equation. Introduction to the principles of Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI) : magnetic Bloch equations, spin echoes, Fourier Transform NMR, basic MRI pulse sequences. Introduction to scattering theory (concept of cross section).
