Abstract:

Three major results of this program are described 1 Raman-induced resonance imaging is used to measure the distribution of atoms in a magneto-optical trap 2 Nonoptical sources of heating in atom traps are explored theoretically. including laser-noise induced heating in optical traps and quantum-diffractive background gas collision-induced heating in shallow magnetic or optical traps 3 An ultrastable CO2 laser trap is demonstrated that achieves a 1e lifetime of 300 sec, the longest ever obtained with an all-optical trap. This enables exploration of s-wave interactions in a weakly interacting, ultracold Fermi gas.
