Tracing the mid-infrared fine structure of quasi-1D excitons controlled by magnetic order
In a joint experiment-theory study, phase-locked mid-infrared pulses trace internal transitions of quasi-1D excitons in CrSBr revealing a strong anisotropy-induced fine-structure splitting. The internal structure changes from strongly-bound, monolayer-localized to weakly-bound, interlayer-delocalized states across the magnetic phase transition.
