Driving strongly correlated electron systems far from equilibrium can lead to fundamentally new many-body phenomena that are thermally inaccessible. In this talk, I will describe a series of recent experiments that leverage advanced ultrafast optical spectroscopic techniques to uncover transient properties of Mott insulators driven by intense electromagnetic fields. By tailoring the characteristics of the electromagnetic field, I will show how different out-of-equilibrium phenomena can be selectively realized. In particular, I will highlight the control of magnetic order using resonant driving, the nonlinear production of electron-hole pairs via off-resonant driving, and coherent “Floquet” engineering of electronic band structures and optical properties via far off-resonant driving.
