Acoustic Non-Abelian Topological Insulator Induced by Artificial SU(2) Gauge Fields (opens in new tab)

Author(s): Haonan Wang, Hui Liu, Zhancheng Li, Yuanshuo Liu, Weiyin Deng, Hua Cheng, Zhengyou Liu, and Shuqi ChenNon-Abelian topological insulators, arising from a non-Abelian gauge field, not only link to particle physics and the strong and weak forces of nature, but also create coveted topological phenomena with remarkable properties. Although significant efforts have been made to develop artificial non-Abel…[Phys. Rev. Lett. 136, 256603] Published Tue Jun 23, 2026
