Many-Body Amplification of Ligand Instabilities Driving Verwey-Type Transitions in Altermagnet CsCr${}_2$S${}_2$O

Xiuhua Chen, Yilin Wang

Altermagnet CsCr${}_2$S${}_2$O undergoes a Verwey-type metal-to-insulator transition (MIT), accompanied by a lattice distortion and stripe charge order on the Cr sublattice. Intriguing…
