A tunable SU(2) gauge field has been realized experimentally in a Raman momentum lattice using ultracold atoms. The chiral dynamics of the system have been investigated under different gauge potentials, whose non-Abelian nature was confirmed through observation of the non-Abelian Aharonov–Bohm effect.

合成 SU(2) 规范场下晶格中的非阿贝尔手征动力学


使用超冷原子在拉曼动量晶格中通过实验实现了可调谐 SU(2) 规范场。在不同规范势下研究了该系统的手性动力学，通过观察非阿贝尔阿哈罗诺夫-玻姆效应证实了其非阿贝尔性质。
