Fundamental Limit to Atom-Ion Sympathetic Cooling in Paul Traps
Atom-Ion Sympathetic Paul Traps Atomic Physics
2012/5/31
We present a fundamental limit to the sympathetic cooling of ions in radio-frequency traps using cold atoms. The limit arises from the work done by the trap electric field during a long-range ion-atom...
Van der Waals-Casimir-Polder interaction of an atom with a composite surface
Van der Waals-Casimir-Polder interaction atom composite surface Atomic Physics
2012/5/29
We study the dispersion interaction of the van der Waals and Casimir-Polder (vdW-CP) type between a neutral atom and the surface of a metal by allowing for nonlocal electrodynamics, i.e. electron diff...

2012/5/28
The use of Raman laser generated by modulation for light-pulse atom interferometer allows to have a laser system more compact and robust. However, the additional laser frequencies generated can pertur...

Total angular momentum representation for atom-molecule collisions in electric fields
Total angular momentum representation atom-molecule collisions electric fields
2012/2/28
It is shown that the atom-molecule collision problem in the presence of an external electric field can be solved using the total angular momentum representation in the body-fixed coordinated frame, le...

2012/2/28
We propose a mechanism for producing Fock states on demand leaking from a single mode optical cavity interacting with a single atom and a laser pulse. The number of photons can be chosen, as it is det...

Three-Axis Measurement a Cold Atom Experiment
2011/8/29
Many experiments involving cold and ultracold atomic gases require very precise control of magnetic elds that couple to and drive the atomic spins. Examples range from quantum transport,entanglement ...

2010/11/16
We demonstrate that the Auger decay rate in an endohedral atom is very sensitive to the atom's location in the fullerene cage. Two additional decay channels appear in an endohedral system: (a) the cha...
