Intertwined polar, chiral, and ferro-rotational orders in a rotation-only insulator
Weizhe Zhang, June Ho Yeo, Xiaoyu Guo +8
Intertwined orders refer to strongly coupled and mutually dependent orders that coexist in correlated electron systems, often underpinning key physical properties of the host mater…
