Summary

Appendix J: mechanical effects of light on matter. The appendix first derives the two forces exerted by a light beam on an atom: the radiation pressure force and the dipole force. Appropriate combinations of beams lead to a friction force that slows the atoms (Doppler cooling), and to a trapping force in the so-called magneto-optics trap (MOT). One then considers the forces exerted on ions, leading to trapping in a suitable geometry of electrodes and fields. Two configurations are used, named Paul and Penning traps. In addition, it is possible to cool the ions to their ground motional state using sideband cooling. It is also possible to trap and cool macroscopic nano-objects, such as microdiscs, membranes, toroids, etc. in a resonant optical cavity.
