9876845ThomasThe objective of this research project is to develop an ultrastable CO2 laser trap for Li-6 fermions. The proposed system offers many opportunities for exploring new physics in the cooling mechanisms and in the interparticle interactions, both in the nondegenerate and quantum degenerate regimes. Efforts within the program comprise broad studies of the trap dynamics including: 1) precooling and loading from a magneto-optical trap; 2) demonstration of very long trap lifetimes; 3) inelastic collisions; 4) optical cooling of the trapped atoms; 5) laser noise-induced heating; and 6) modeling of focused gaussian beam traps.

这个研究项目的目标是为Li-6费米子开发一个超稳定的CO2激光陷阱。该系统为探索非简并态和量子简并态的冷却机制和粒子间相互作用的新物理提供了许多机会。该计划的工作包括对陷阱动力学的广泛研究，包括：1)磁光陷阱的预冷和加载；2)非常长的圈闭寿命证明；3)非弹性碰撞；4)捕获原子的光学冷却；5)激光噪声加热；6)聚焦高斯束阱的建模。
