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两电子相互作用和原子之间的相干碰撞。该项目是PI团队内部更大努力的一部分，该团队专注于使用激光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相当感兴趣的一个领域。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的一个长期存在的问题，尚无已知的一般解决方案。第二条线的实验将测试一种不同的频域标度能谱在强静电场存在下研究复杂的多组态两电子动力学的普遍适用性。在第三组实验中，将探索通过共振里德堡-里德堡原子碰撞转移原子相干性。更广泛的影响涉及研究生和本科生的教育。
