稀薄量子系统中的接触量和普适关系

Contact and universal relations in dilute quantum systems

  • 摘要: 对接触量和普适关系的发现是超冷原子物理中的一个重大理论突破。自檀时钠于2005年首次指出接触量这个概念以来,对普适关系的研究已经成为冷原子物理中的一个重要课题,并对其他相关的领域产生了重大的影响。文章介绍了什么是接触量和普适关系,以及普适关系的来源,并讨论在这个研究方向上最新的一些进展,包括高分波散射的接触量和接触量谱。

     

    Abstract: The discovery of contact and universal relations is a breakthrough in the field of ultracold atom physics. Since S. Tan first pointed out the concept of contact in 2005, the study of universal relations has become an important subject regarding ultracold atoms, and has had a significant impact on related fields. This article gives an introduction on what are contact and universal relations, and their origins. Recent new developments including contact in high partial wave scattering and contact spectrum are also discussed.
