Studies Involving Atoms in High Rydberg States

实验研究计划是一个项目，继续进行实验，研究原子的非常高的里德伯态的动力学：那些主量子数接近400。 处于这种高里德堡态的电子具有足够长的经典开普勒周期，以允许应用受控电场脉冲和脉冲序列，这些脉冲序列的持续时间短于经典开普勒周期或与经典开普勒周期相当。这些实验的目的是利用这些高里德伯态来研究“被踢原子”，这是一个模型，用于研究非线性动力学的哈密顿系统。 测量将发生在一个制度，预计量子局域化将变得重要，这应该给洞察经典量子对应。第二组实验，提出研究如何里德伯原子与表面相互作用。 主要目标是确定内部原子状态在接近表面时如何演变，以及如何影响电荷转移动力学。 更广泛的影响涉及到学生的教育，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.
