A Program in Ultralow-Temperature Atomic Physics

这个超低温原子物理学项目是基于对玻色爱因斯坦凝聚（BEC）现象的利用。 玻色爱因斯坦凝聚实现了一类新的气态量子流体，研究这类新流体的性质是本课题的一个目标。 这些属性包括集体激励，特别强调的流体动力学制度，相干性，凝聚物在旋转框架，和凝聚物的行为附近的Feshbach共振。 科学目标将伴随着操纵冷凝物的进展。 使用光束扫描技术的灵活的光学设置将允许实现各种各样的捕获潜力。 最后，本研究利用凝聚体的性质应用于原子光学。

This project in ultralow-temperature atomic physics is based on the exploitation of the phenomenon of Bose Einstein Condensation (BEC). Bose Einstein condensates realize a new class of gaseous quantum fluid, and one goal of the research is to study the properties of this new fluid. These properties include collective excitations with special emphasis on the hydrodynamic regime, coherence properties, condensates in rotating frames, and the behavior of condensates near Feshbach resonances. The scientific goals will be accompanied by advances in manipulating condensates. A flexible optical setup using beam scanning techniques will allow the realization of a great variety of trapping potentials. Finally, the research exploits the properties of condensates for application to atom optics.
