Description
Recent advances in laser technology and nanoplasmonics, combined with heavy-ion collisions leads to a new, previously untamed road towards fusion energy production research. Here we explore recent advances in the theoretical, simulation part of the NAno-Plasmonic Laser Inertial confinement Fusion Experiment (NAPLIFE). We study how gold nanoparticle doping enhances medium absorption under laser infrared pulses at intensities between $10^{15}$ and $10^{18}$ W/cm$^2$. Contrary with tradition, we simulate the nanoparticles with the particle-in-cell method, this also makes investigation of other effects possible, that cannot be considered with common methods, such as electron spillouts. We compare various shapes and sizes of dopes, focusing on the ejection dynamics of conducting electrons and tracking the interaction between the laser radiation and the doped matter, monitoring ionization products and their energies, as well as field intensities around the resonating nanoantennas.
