This book chapter gives an introduction to, and an overview of, methods for
cooling trapped ions. The main addressees are researchers entering the field.
It is not intended as a comprehensive survey and historical account of the
extensive literature on this topic. We present the physical ideas behind
several cooling schemes, outline their mathematical description, and point to
relevant literature useful for a more in-depth study of this topic.Comment: Part of the Proceedings of the Les Houches Winter School on the
Physics with Trapped Charged Particles held in January 2012. References
