Quantum electronics: The electron is cool
Peter E. Toschek
Abstract
Temperature is an awkward concept for a single particle, but the energy of the particle's 'quivering' is a useful substitute. Feedback control of this motion can be used to cool a single electron to very low temperature.
Individual electrons, trapped by electric and magnetic fields, can be used for precise, fundamental measurements. D'Urso, Odom and Gabrielse1 now report in Physical Review Letters that they have succeeded in controlling the residual random motion of a trapped electron using feedback signals.
