RUI: Cold Atoms and Atomic Lifetimes and Engineering

RUI的活动包括三个涉及原子物理学的项目。第一个计画是利用空芯光子带隙光纤导引冷原子。这种光纤可以传输光和冷原子在单一的光学和原子的德布罗意布罗意模式。第二个项目是开发黑洞陷阱。冷原子将使用磁光阱产生，然后将被转移到另一个原子状态，并被陷阱中心的黑洞捕获。这个黑洞陷阱应该允许产生非常高的原子密度。最后一个项目是利用锁模激光测量原子寿命的新技术。该技术将用于改进铯原子激发态寿命的测量。更广泛的影响涉及本科生的教育和传感器的应用。

This RUI activity consists of three projects involving atomic physics. The first project involves cold atom guiding ina hollow core photonic bandgap fiber. This fiber can transport both light and cold atoms in single optical and atomic de Broglie modes. The second project is the development of a black hole trap. Cold atoms will be produced using a magneto-optical trap and then will be transferred to another atomic state and captured by a black hole at the trap center. This black hole trap should allow production of very high atomic densities. The last project is a new technique for the measurement of atomic lifetimes using mode locked lasers. This technique will be used for improved measurement of lifetimes for excited states in atomic cesium. The broader impact involves the education of undergraduate students and the applications to sensors.
