Abstract
Photoemission of electrons from atoms or metals is a fundamental process in radiation-matter interaction and has been studied extensively using lasers (see e.g. [1]). Strong-field photoemission enhanced by plasmonic nanoparticles was recently shown [2]. Electron emission driven by high-intensity light fields is accompanied by high-harmonic generation (HHG), a process forming the basis for attosecond technology. Enabled by recent development of high-intensity THz sources, HHG driven by intense multi-THz transients was also demonstrated [3].
