Abstract

Ultracold molecules formed from association of a single Rydberg atom with surrounding atoms or molecules and those from double Rydberg excitations are discussed in this review. Ultralong-range Rydberg molecules possess a novel molecular bond resulting from scattering of the Rydberg electron from the perturber atoms or molecules. The strong interactions between Rydberg atoms in ultracold gases may lead to formation of macroscopic Rydberg macrodimers. The exquisite control over the properties of the Rydberg electron means that interesting and unusual few-body and quantum many-body features can be realized in such systems.

摘要

本文讨论了由单个里德伯原子与周围原子或分子缔合形成的超冷分子和双里德伯激发形成的超冷分子。超远距离里德伯分子具有一种新的分子键，这种键是由里德伯电子从扰动原子或分子上散射产生的。超冷气体中里德伯原子之间的强相互作用可能导致宏观里德伯大聚合物的形成。对里德伯电子性质的精确控制意味着在这样的系统中可以实现有趣和不寻常的少体和量子多体特征。
