Collective electron dynamics in plasmonic nanosystems can unfold ontimescales in the attosec- ond regime and the direct measurements of plasmonicnear-field oscillations is highly desirable. We report on numerical studies onthe application of attosecond nanoplasmonic streaking spectroscopy to themeasurement of collective electron dynamics in isolated Au nanospheres. Theplasmonic field oscillations are induced by a few-cycle NIR driving field andare mapped by the energy of photoemitted electrons using a synchronized,time-delayed attosecond XUV pulse. By a detailed analysis of the amplitudes andphase shifts, we identify the different regimes of nanoplasmonic streaking andstudy the dependence on particle size, XUV photoelectron energy and emissionposition. The simulations indicate that the near-fields around thenanoparticles can be spatio-temporally reconstructed and may give detailedinsight into the build-up and decay of collective electron motion.
