  Recently laser induced fusion with simultaneous volume ignition, a spin-off
from relativistic heavy ion collisions, was proposed, where implanted nano
antennas regulated and amplified the light absorption in the fusion target.
Studies of resilience of the nano antennas were published recently in vacuum
and in UDMA-TEGDMA medium. These studies concluded that the lifetime of the
plasmonic effect is longer in medium, however, less energy was observed in the
UDMA-TEGDMA copolymer, due to the smaller resonant size of gold nanoantenna
than in case of Vacuum. Here we show how the plasmonic effect behaves in an
environment fully capable of ionization, surrounded by Hydrogen atoms close to
liquid densities. We performed numerical simulations treating the electrons of
gold in the conduction band as strongly coupled plasma. The results show that
the protons close to the nanorod's surface follow the collectively moving
electrons rather than the incoming electric field of the light. The results
also show that the plasmonic accelerating effect is also dependent on the laser
intensity.
