The nature of correlated insulator states commonly observed in moiré superlattices are still under investigation. Here, the authors use pump-probe spectroscopy to study the dynamics of correlated insulator states in a WSe2/WS2 moiré heterostructure at two different fillings, elucidating distinct time-domain signatures associated with these states.
