Towards magnetic slowing of atoms and molecules
We outline a method to slow paramagnetic atoms or molecules using pulsed magnetic fields. We also discuss the possibility of adiabatically slow trapped particles by decelerating a moving magnetic trap. We present numerical simulation results for the slowing and trapping of molecular oxygen.
متن کاملLaser cooling and trapping of neutral atoms*
In 1978, while I was a postdoctoral fellow at MIT, I read a paper by Art Ashkin (1978) in which he described how one might slow down an atomic beam of sodium using the radiation pressure of a laser beam tuned to an atomic resonance. After being slowed, the atoms would be captured in a trap consisting of focused laser beams, with the atomic motion being damped until the temperature of the atoms ...
متن کاملLaser Cooling and Trapping of Neutral Atoms
This article presents a review of some of the principal techniques of laser cooling and trapping that have been developed during the past 20 years. Its approach is primarily experimental, but its quantitative descriptions are consistent in notation with most of the theoretical literature.
متن کاملLaser Cooling and Trapping of Neutral Atoms
The ability to cool, manipulate, and trap atoms using laser light has allowed a new, rapidly expanding field to emerge. Current research focuses on improving existing cooling techniques, and the development of cold atoms as a source for applications ranging from atomic clocks to studies of quantum degeneracy. This review explains the basic mechanisms used in laser cooling and trapping, and illu...
متن کاملControlling the interactions between cold Rydberg atoms by a time-varying electric field
Long-range interactions between cold Rydberg atoms are being investigated for neutral-atom quantum computing, quantum simulations, phase transitions in cold Rydberg gases and other applications. Fine tuning of the interaction strength can be implemented using Förster resonances between Rydberg atoms controlled by an electric field. The observation of the Stark-tuned Förster resonances between R...
