New trap design offers potential for single atom preparation in research.
Researchers studied a new trap for capturing rubidium atoms called the focused-beam trap (FBT). They compared it to the standard trap (MOT) and found that the FBT can hold fewer atoms but has unique advantages. By adjusting trap parameters, they identified conditions for loading atoms into a different trap called the far-off-resonance optical dipole trap (FORT). The FBT's design allows for easier access to the atoms and may be useful for preparing single atoms for experiments.
