| Sumario: | <HTML>Prof.<B> C. Cohen-Tannoudji</B> presents <B> "manipulating atoms with light" </B>. <BR>By using quasi-resonant exchanges of energy, linear and angular momentum between atoms and photons, it is possible to polarize atoms, to displace their energy levels and to control their position and their velocity. A few physical mechanisms allowing one to trap atoms and to cool them in the microKelvin, and even in the nanoKelvin range, will be described. Various possible applications of such ultracold atoms will be also reviewed.</BR> |
