Laser-cooling and Optical Trapping of Diatomic Molecules

Ultracold molecules have been proposed as a rich resource for many applications ranging from precision measurements and quantum metrology to quantum simulation and quantum information processing. The benefits of molecules in all these applications arise from the many internal degrees of freedom in a molecule. For example, even with the simplest two-atom diatomic molecules, one...
