U. S. Germany Cooperative Research: Coherent Preparation of High-Contrast Atomic Dark States

0090128烹饪该奖项支持约翰·基廷和科罗拉多大学的学生，他们与德国波恩大学应用物理系的罗伯特·韦恩兹合作。这项由该奖项资助的研究将研究如何提高三能级原子系统中暗线共振的信号强度，这对磁学和原子钟研究都具有重要意义。与测量小吸收有关的问题限制了时钟参考频率和磁力计灵敏度的稳定性。这一研究结果将有助于波恩的磁测量工作以及科罗拉多大学和美国国家科学技术研究院的原子钟研究，因为这两个领域都依赖于激发和测量碱原子中超精细跃迁的物理学。这种合作不仅有助于更好地理解潜在的物理学，而且还将导致目前在每个领域单独使用的技术方法的实际交流。这种联合、合作的研究努力为初级研究人员带来了巨大的机会，就这一提议所做的工作将有助于使德国和美国研究小组之间的关系制度化。

0090128KitchingThis award supports John Kitching and students from the University of Colorado in a collaboration with Robert Wynands of the Applied Physics Department at the University of Bonn, Germany. The research funded by this award will study ways to increase the signal strength of dark-line resonances in three-level atomic systems, which are significant for both magnetometry and atomic clock research. Problems associated with the measurement of the small absorption limits the stability of clock reference frequencies and magnetometer sensitivities. The results of this research will be of benefit to the magnetometry work at Bonn and to the atomic clock research at the University of Colorado and at NIST, since both fields rely on the physics of exciting and measuring hyperfine transitional in alkali atoms. Not only will this collaboration lead to a better understanding of the underlying physics, but will also lead to a practical exchange of technological methods now used in each field individually. The opportunity this joint, collaborative research effort presents junior researchers is substantial, and the work done on this proposal will help institutionalize the relationship between the German and U.S. research groups.
