In the realm of ultrafast science, a new field of research has emerged involving the study of strong-field interactions in solid-state nanostructures and dielectric media [1]. By using nanostructures, specifically those made out of metals, external electromagnetic fields can be localized on length scales of just a few nanometers, resulting in significantly enhanced field amplitudes that can exceed those of the external field by orders of magnitude in the vicinity of the nanostructures. In addition to the interesting strong-field aspect of this scenario, I will cover ultrafast/nonlinear processes in solids where we exploited hot electron generation for ultrafast switching [2] and ultrafast current control and in solids [3] with which we built an optical chip for 3D carrier-envelope phase scanning [4].
