Fluctuation Electromagnetic Interaction Between Small Rotating Particle and a Surface

Abstract

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.
