Abstract: Strong-field physics, an extreme limit of light-matter interaction, is expanding into the realm of surfaces and nanostructures from its origin in atomic and molecular science. The attraction of nanostructures lies in two intimately connected features: local intensity enhancement and sub-wavelength confinement of optical fields. Local intensity enhancement facilitates access to the strong-field regime and has already sparked various applications, whereas spatial localization has the potential to generate strong… Show more

“…Recently, even higher nonlinear effects such as above-threshold and strong-field photoemission and acceleration were observed in plasmonic and other nanostructures [12,62,63,17,15,64], closing the gap to strong-field and attosecond physics. [13,14] Another key example of this development was the report of high-harmonic generation (HHG) in plasmonic bow-tie antennas [24], that is, the integration of the most prominent strong-field effect of gaseous media [20,33] into a nanostructure. Despite triggering widespread theoretical [46,65,66,67] and experimental [26,28] efforts, subsequently, this effect has remained rather elusive.…”

“…Numerous characteristic nonlinear optical phenomena, such as above-threshold and strongfield photoemission, have become accessible using local field enhancements in metal nano-tips [12,62,13,14,15], resonant optical antennas [24,28,16,81], nanoparticles [17], rough surfaces [63], and plasmonic waveguides [26,15]. These experimental studies are paralleled by increasing theoretical efforts of describing strong-field effects at surfaces and in optical near fields [82,83,64], with a particular emphasis on nanostructure-enhanced high-order harmonic generation (HHG) [46,65,66,84,67,85,86,87,88,89,90].…”
