Quantum control in 2D materials via ultrafast nonlinear optics

<h2>Summary</h2> Revealing and manipulating intricate quantum phenomena in two-dimensional (2D) materials is challenging, due to their complex many-body, coherent, and non-equilibrium characteristics. Ultrafast nonlinear optics, sensitive to precisely these many-body and coherent processes, provides powerful approaches. These emerging techniques enable direct probing of quantum effects, many-body interactions, and non-equilibrium states. In this perspective, we concisely review recent physical insights into 2D materials unveiled by ultrafast nonlinear optical techniques and outline promising future directions. We anticipate that these optical techniques will be instrumental in unraveling the mysteries of novel physics in 2D materials and paving the way for next-generation quantum devices.
