Electromagnetic trapping of cold atoms

This review describes the methods of trapping cold atoms in electromagnetic fields and in the combined electromagnetic and gravity fields. We discuss first the basic types of the dipole radiation forces used for cooling and t rapping atoms in the laser fields. We outline next the fundamentals of the laser cooling of atoms and classify the temperature limits for basic laser cooling processes. The main body of the review is devoted to discussion of atom traps based on the dipole radiation forces, dipole magnetic forces, co mbined dipole radiation-magnetic forces, and the forces combined of the dip ole radiation-magnetic and gravity forces. Physical fundamentals of atom tr aps operating as waveguides and cavities for cold atoms are also considered . The review ends with the applications of cold and trapped atoms in atomic , molecular and optical physics.
