Fluctuation Electromagnetic Interaction Between Small Rotating Particle and a Surface
摘要：
研究了中性旋转小粒子与可极化表面的涨落电磁相互作用。粒子的极化和表面近场的起伏产生了吸引力、摩擦力矩和加热。封闭的解析表达式被发现这些量假设的颗粒和表面的特征在于由频率依赖的极化率和介电常数和不同的温度。结果表明，滚动粒子在表面近场的停留时间远小于真空空间中匀速运动和滚动时的停留时间。
英文摘要：
We study fluctuation electromagnetic interaction between small neutral rotating particle and polarizable surface. The attraction force, friction torque and heating are produced by the particle polarization and fluctuating near-field of the surface. Closed analytical expressions are found for these quantities assuming that the particle and surface are characterized by the frequency dependent polarizability and dielectric permittivity and different temperatures. It is shown that the stopping time of the rolling particle in the near-field of the surface is much less than the stopping time under uniform motion and rolling in vacuum space.
