Light and Surface Plasma Wave Induced Force on Nanoparticles and Nanotubes

Santosh Jain, J. Parashar and Rajnish Kurchania

Expressions for force on spherical nanoparticles and cylindrical nanotubes due to laser and surface plasma wave are obtained. It shows Expressions for force on spherical nanoparticles and cylindrical nanotubes due to laser and surface plasma wave are obtained. It shows resonant enhancement at ω=ω p/√3 for the nanoparticle and ω=ω p/√2 for the nanotube. At frequencies lower than this resonance the ponderomotive force is along the intensity gradient of the laser while antiparallel for frequencies higher than the resonant frequency.
