In this talk I’ll summarize the theoretical work we have done to tackle the underlying physics of laser-matter processes driven by spatially and temporal synthesized fields, with a main emphasis in above-threshold ionization (ATI) and high-order harmonics generation (HHG) in atoms induced by plasmonic fields. It is well known that one of the main theoretical assumptions in the modelling of laser-matter phenomena is that the laser electric field is spatially homogeneous in the region where the electron dynamics takes place. When we relax this premise, i.e. when the laser electric field presents variations at a nanometric scale, we open a new and appealing scenario. By using classical, semiclassical and quantum mechanical theoretical tools we were able to shed some light about the modifications produced by spatially inhomogeneous fields -fields which present spatial variations in a scale comparable to the one of the electron dynamics. I will also discuss about the experimental challenges we face, in order to confirm our predictions, and alternative approaches we thought could be more plausible to implement.
