We predict the electromagnetic field driven nucleation of nanoparticles that
provide plasmonic oscillations in resonance with the field frequency. The
oscillations assume a phase that maximizes the particle polarization and energy
gain due to nucleation. We derive closed form expressions for the corresponding
nucleation barrier and particle shape vs. field frequency and strength, metal
plasma frequency, conductivity, and the host dielectric permittivity. We show
that the plasmonic polarization allows for nucleation of particles that would
not be stable in zero field.Comment: 5 pages, 3 figure
