Coupled Spin-Density-Wave and Bond-Order Driven Metal-Insulator Transition in Altermagnetic CsCr${}_2$S${}_2$O

Chenchao Xu, Wansheng Bai, Guo-Xiang Zhi +4

A metal-insulator transition (MIT) driven by bond order (BO) coupled with a secondary spin-density wave (SDW) is identified in CsCr${}_2$S${}_2$O. Such coupling is enabled as a result…
