Studies Involving Atoms in High Rydberg States

实验研究计划是一个项目，目的是继续进行实验，研究原子的超高里德堡态的动力学：那些主量子数接近400的原子。处于如此高里德堡态的电子具有足够长的经典开普勒周期，以允许施加比经典开普勒周期更短或与之相当的受控电场脉冲和脉冲序列。这些实验的目的是利用这些高里德堡态来研究哈密顿系统的非线性动力学模型--“踢原子”。测量将在一个预计量子局域化将变得重要的区域进行，这将使我们深入了解经典-量子对应。第二组实验是用来研究里德堡原子如何与表面相互作用的。主要目标是确定内部原子态在接近表面时如何演变，以及如何影响电荷转移动力学。更广泛的影响包括对学生的教育，对经典-量子边界附近的非线性动力学研究的影响，以及表面表征。

The experimental research program is a project to continue experiments performed studying the dynamics of extraordinarily high Rydberg states of atoms: those with principal quantum numbers near 400. Electrons in such high Rydberg states have classical Kepler periods that are long enough to allow the application of controlled electric field pulses and sequences of pulses that are shorter than or comparable in duration to the classical Kepler period. The goal of these experiments is to use these high-Rydberg states to study the "kicked atom" which is a model for the study of nonlinear dynamics of Hamiltonian systems. The measurements will take place in a regime where it is expected that quantum localization will become important, which should give insight into classical-quantum correspondence. A second set of experiments is proposed to study how Rydberg atoms interact with surfaces. The main goal is to determine how the internal atomic state evolves as they approach a surface and how that affects charge-transfer dynamics. The broader impacts involve the education of students, impact on studies of nonlinear dynamics near the classical-quantum boundary, and surface characterization.
