This experiment research project focuses on an exploration of energy transport in ultracold gases coupled by long range dipole-dipole interactions. The proposed experiments will explore the diffusion of energy through a sample of Rydberg atoms. This work is related to several experiments proposed or currently underway in ultracold ground-state atoms and molecules. The focus of all of these experiments is on the impact of nonisotropic potentials on the dynamics of many-body systems with the goal of gaining insight into condensed-matter systems, plasma systems, and ultracold gases. The proposed experiments will build on prior work by creating spatially structured samples of Rydberg states and exploring the spatial redistribution of the energy using a spatially sensitive detector which the group has recently constructed. Computational analysis and modeling of the experiments will also be performed. The broader impact of this work is in its connection to ultracold gas studies and condensed matter physics, and in its educational impact on graduate students and the undergraduate research of women students at Bryn Mawr College.

本实验研究项目的重点是探索远距离偶极-偶极相互作用耦合的超冷气体中的能量输运。提出的实验将探索能量通过里德伯原子样本的扩散。这项工作与几个在超冷基态原子和分子中提出或正在进行的实验有关。所有这些实验的重点是非各向同性势对多体系统动力学的影响，目的是深入了解凝聚态系统、等离子体系统和超冷气体。提出的实验将建立在先前工作的基础上，通过创建里德堡态的空间结构样本，并使用该小组最近构建的空间敏感探测器探索能量的空间再分配。还将进行实验的计算分析和建模。这项工作的广泛影响在于它与超冷气体研究和凝聚态物理的联系，以及它对研究生和布林莫尔学院女学生的本科研究的教育影响。
