First-principle N-body simulations by Charles Varin (University of Ottawa) and collaborators with the HPC simulation engine MicPIC reveal the extreme dynamics of a nanoplasma driven by intense femtosecond infrared radiation. When the laser field is intense enough to pull a substantial amount of the electrons periodically in and out of the object surface, small internal fluctuations develop into collective oscillations of the charge density and associated electric field. These semi-spherical plasma waves converge to the center of the nano-object and meet. The resulting turbulent plasma dynamics leads to giant density and field fluctuations that evolve on the attosecond time scale. This visualization of the electric field intensity inside a light-driven 60-nm nanoplasma was made with MayaVi.
