Competing exotic phases of matter emerge in quantum materials due to complex interactions between charge, lattice, spin, and orbital degrees of freedom. The control of their macroscopic properties via external perturbations is essential to the realization of new technological applications. Ultrafast light-matter coupling enables unique mechanisms to access new out-of-equilibrium phases of matter in a controlled and reversible manner, which can then be harnessed towards next-generation technology .
In this talk, I will discuss how the discovery of ultrafast nonthermal critical behavior in a Mott insulator has implications for future THz spintronic technology . Additionally, I will introduce recent experimental results extending time-resolved spectroscopic techniques to the 2D atomic limit  aiming to combine ultrafast light-matter interaction with Van-der-Waals devices.
