Localization of Light in High-density Ultracold Atomic Vapors

重点测量了在强局域光条件下，光与超冷RB-87原子相互作用的时间、空间和频率依赖关系。特别令人感兴趣的是从这样一个样品中发出的光的时间演化，它可以揭示经典扩散的抑制和强烈局域化的开始。还描述了一种产生在稠密蒸汽中产生共振局域辐射物质激发所必需的内部原子激发的方法。更广泛的影响涉及教育、基础设施和多样性。

This proposes focuses on the measurement of the time, spatial, and frequency dependence of light interacting with a sample of ultracold Rb-87 atoms in the strong localization of light regime. Of particular interest is the time evolution of light emerging from such a sample, which can reveal suppression of classical diffusion and the onset of strong localization. Also described is a method of generating the internal atomic excitation necessary to produce resonant localized radiation-matter excitations within the dense vapor. The broader impact involves education, infrastructure and diversity.
