Ultrafast coupled charge and spin dynamics in strongly correlated NiO

Nickel Oxide (NiO) is a strongly correlated insulator with antiferromagnetic (AFM) ordering. Here, using pump-probe photoemission on NiO, the authors observe coherent terahertz oscillations in the photoemission signal, a signature of an in-gap state coupled to the AFM background.
