This project focuses on the study of the effects of varying the strength of the atomic interactions in a binary, two-spin-state Bose-Einstein Condensate in Rb-87. Two avenues of research will be pursued. In the first series of experiments the physics of a Feshbach resonance will be uniquely examined using the double-condensate system. In these experiments the second condensate component is used as a tool that permits approaching the resonance suddenly from both sides, and in a novel manner. In the second series of experiments the Feshbach resonance will be used to create binary Bose fluid systems of varying interaction strengths, with a particular emphasis on the physics of component separation. In this set of experiments the second component serves as a phase reference for interferometric studies of a condensate in the vicinity of a resonance.

该项目的重点是研究Rb-87中二元双自旋态玻色-爱因斯坦凝聚体中原子相互作用强度变化的影响。 将采取两种研究途径。 在第一系列的实验中，Feshbach共振的物理学将使用双凝聚系统进行独特的检查。 在这些实验中，第二冷凝组分被用作允许从两侧以新颖的方式突然接近共振的工具。 在第二系列实验中，Feshbach共振将用于创建不同相互作用强度的二元玻色流体系统，特别强调组分分离的物理学。 在这组实验中，第二个组件作为一个相位参考的干涉研究的凝聚体附近的共振。
