This research focuses on the manipulation of two-electron interactions within atoms and coherent collisions between atoms. The project is part of a larger effort within the PI's group that focuses on using lasers to control and observe quantum dynamics in atoms and molecules, an area of considerable current interest in fundamental physics research. In one set of experiments, electronic wavepacket control techniques will be used to investigate electron dynamics in a three-body Coulomb system, a long-standing problem in quantum and classical physics with no known general solution. A second line of experiments will test the general applicability of a variant of frequency-domain scaled-energy spectroscopy for investigating complex multi-configurational two-electron dynamics in the presence of strong static electric fields. In a third group of experiments, the transfer of atomic coherence via resonant Rydberg-Rydberg atom collisions will be explored. The broader impact involves the education of both graduate and undergraduate students.

这项研究的重点是操纵原子内的双电子相互作用和原子之间的相干碰撞。该项目是 PI 小组内一项更大努力的一部分，该小组的重点是使用激光来控制和观察原子和分子中的量子动力学，这是当前基础物理研究中备受关注的领域。在一组实验中，电子波包控制技术将用于研究三体库仑系统中的电子动力学，这是量子和经典物理学中长期存在的问题，没有已知的通用解决方案。第二行实验将测试频域标度能量谱的变体的普遍适用性，用于研究强静电场存在下的复杂多构型双电子动力学。在第三组实验中，将探索通过共振里德伯-里德伯原子碰撞来转移原子相干性。更广泛的影响涉及研究生和本科生的教育。
