Plasmonic-field reconstruction with atomic spatiotemporal resolution
Abstract
We propose schemes for reconstructing induced plasmonic fields at the surface of isolated nanoparticles from infrared-streaked extreme-ultraviolet photoemission spectra with sub-femtosecond temporal and sub-nanometer spatial resolution. We image the plasmonic fields using both quantum-mechanical and a classical models that are valid for different ranges of laser and XUV-pulse parameters. The applicability of each method will be discussed for different pulse characteristics. Our numerical applications to Au nanospheres demonstrate highly accurate plasmonic field retrievals.
