项目摘要
This project is a collaborative effort between Bryn Mawr College and Ursinus College in which we are exploring the coherent control of interactions among ultracold Rydberg atoms with a combination of experimental and computational efforts. When atoms in an ultracold gas are excited to weakly bound Rydberg states, they can exchange energy through a dipole-dipole interaction. In many cases this energy exchange proceeds quickly enough that the atoms are essentially stationary, resembling an amorphous solid. This leads to complicated many-body processes during the energy exchange that can be manipulated with a variety of techniques. We are focusing our efforts on coherently controlling the dipole-dipole energy exchange among atoms by exciting coherent superpositions of initial states, arranging the Rydberg atoms in particular spatial patterns, and manipulating the geometry and timing of the electric field used to tune this energy exchange into resonance. These experiments are helping to expand the toolkit for controlling atomic interactions. We are modeling the experiments using parallel computing resources in order to contribute to the understanding of the complex many-body interactions.Cold Rydberg atoms provide a rich system in which to explore a range of fundamental physics that is of interest to a broad segment of the community. The precision with which both the internal structure of each atom and the spatial arrangement of these atoms can be controlled will allow us to study many-body and correlation effects for a range of configurations. The interest in ultracold gases coupled by long range dipole-dipole interactions has grown rapidly in recent years and is being explored using atoms with large magnetic spins and heteronuclear molecules as well as Rydberg atoms.This project will engage undergraduates, with particular attention to attracting female students, at both Bryn Mawr and Ursinus in computational and experimental research on ultracold Rydberg atoms. Bryn Mawr and Ursinus are small, national liberal arts colleges located in close proximity in southeastern Pennsylvania. Bryn Mawr awards a small number of PhDs and this project will also support a graduate student. The collaborative nature of the project will broaden opportunities for students at both institutions.
这个项目是布林莫尔学院和乌尔西诺学院之间的合作努力,我们正在探索与实验和计算工作相结合的超冷里德伯原子之间的相互作用的相干控制。 当超冷气体中的原子被激发到弱束缚里德堡态时,它们可以通过偶极-偶极相互作用交换能量。 在许多情况下,这种能量交换进行得足够快,以至于原子基本上是静止的,类似于无定形固体。 这导致在能量交换过程中复杂的多体过程,可以用各种技术来操纵。 我们的工作重点是通过激发初始态的相干叠加来相干控制原子之间的偶极-偶极能量交换,将里德伯原子排列在特定的空间模式中,并操纵电场的几何形状和定时,以将这种能量交换调谐到共振状态。这些实验有助于扩展控制原子相互作用的工具包。 我们正在使用并行计算资源来模拟实验,以促进对复杂的多体相互作用的理解。冷里德伯原子提供了一个丰富的系统,在其中探索一系列的基础物理,这是感兴趣的社区的广泛部分。 每个原子的内部结构和这些原子的空间排列都可以精确控制,这将使我们能够研究一系列构型的多体效应和关联效应。 近年来,人们对偶极-偶极长程相互作用耦合的超冷气体的兴趣迅速增长,并正在利用具有大磁自旋的原子和异质结分子以及里德伯原子进行探索。本项目将吸引布林莫尔和乌尔西诺的本科生,特别是女学生,参与超冷里德伯原子的计算和实验研究。 布林莫尔学院和乌尔西诺学院都是小型的国立文科学院,位于宾夕法尼亚州东南部。 布林莫尔奖少数博士学位,这个项目也将支持研究生。 该项目的合作性质将扩大学生在这两个机构的机会。
