Abstract

We present calculations on the implementation of attosecond nanoplasmonic streaking (APS) spectroscopy on isolated nanoparticles. APS spectroscopy might enable a remote measurement of plasmonic field oscillations in the optical regime with sub-cycle temporal resolution, where plasmons are excited by a few-cycle near-infrared (NIR) driving field and the associated near-fields are mapped by the energy of photoemitted electrons using a synchronized, time-delayed attosecond extreme ultraviolet (XUV) pulse. We discuss the influence of the near-field spatial distribution and electron kinetic energy on the streaking process. By numerical simulations we show the feasibility of APS spectroscopy using Au nanospheres with 10 nm and 100 nm diameter. We show that the near-elds around the nanoparticles can be spatiotemporally reconstructed and may give detailed insight into the build-up and decay of collective electron motion.
