| Summary: | This study investigates viscous and quantum effects on the collective behavior of surface plasmons on various metals, such as the conventional surface magnetoplasmons and the acoustic surface magnetoplasmons, under the modulations of magnetic field and particle–surface interactions. We calculate wake potential, plasmon density, and stopping power based on a viscous quantum hydrodynamic model. It is observed that viscous effects tend to lower and broaden the peaks of stopping power, wake potential and plasmon density oscillations. Quantum effects modify the position and shape of these peaks, which might be essential for optimizing conditions in processes like materials engineering. The coupling of viscous and quantum effects significantly impacts the excitation of surface magnetoplasmons, with notable variations across different metals, indicating that material properties influence the plasmonic behavior. |
