摘　　要：The hybrid quantum/classical scheme(HQCS) is used for the photoabsorption analysis of metal nanoparticles. The HQCS divides the structure of interest into quantum and classical subsystems. First, we calculate and report Lorentz parameters for gold(Au), silver(Ag), aluminum(Al), chromium(Cr), and nickel(Ni) permittivities used in the classical subsystem. Then, photoabsorption spectra were obtained from HQCS for the single nanoparticle structures with and without two sodium(Na) atoms. The Au, Ag, Al, Cr, and Ni show strong sensitivity to the presence of the atomic subsystem. This work could pave the way for how coupled plasmon modes between metal nanoparticles and atomic structures can be utilized for sensing devices.
