WebCooling and trapping atoms present new possibilities for studies of ultracold atoms and atomic interactions. The techniques of laser cooling and deceleration of atomic beams, magnetic and laser trapping of neutral atoms, and a number of recent advances in the use of radiative forces to manipulate atoms are reviewed. Formats available WebThese pioneering works have formed the basis for two very successful research areas: laser cooling of atoms and optical trapping. Today, these well-developed techniques are common tools for the manipulation of atoms, molecules and particles. For example, optically levitated nanoparticles have been laser-cooled towards their quantum-mechanical ...
