9732632HuletThis work is a continuation of investigations of quantum degenerate trapped gases of lithium-7 atoms. It expands upon the previous observation of the PI that condensation is possible in this negative-scattering-length system, although with a limited number of atoms in the condensate. It focus on a series of experiments to explore the mechanisms by which this limit is enforced and to examine the dynamical behavior of the system. A second effort will focus on looking for a possible BCS-type transition in a cooled sample of lithium-6 atoms.

这项工作是对锂-7原子的量子简并囚禁气体研究的继续。它扩展了之前对等电点的观察，即在这个负散射长度的系统中可能发生凝聚，尽管凝聚体中的原子数量有限。它集中于一系列实验，以探索实施这一限制的机制，并检查系统的动力学行为。第二项工作将专注于在冷却的锂-6原子样本中寻找可能的BCS类型的转变。
