Stopping power of surface magnetoplasmons with viscous and quantum effects in different two-dimensional targets

Year: 2025

Type: article

Abstract: Collective electronic excitation at metal surfaces are widely studied for their crucial role across a broad range of research fields, including fundamental physics and surface science. 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 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 density oscillations, indicating that viscosity dampens the amplitude of these plasmonic features. Quantum effects modify the position and shape of these peaks, reflecting the influence of quantum behavior on electron interactions. 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. This work underscores the necessity of considering both viscous and quantum effects on surface magnetoplasmons to optimize performance and efficiency for applications where precise control of electron dynamics is necessary, such as in surface plasmon resonance sensors and materials science.
