Fluctuation Electromagnetic Interaction Between Rotating Nanoparticle
and Near-Field of the Surface

A. A. Kyasov, G. V. Dedkov
Fluctuation electromagnetic interaction between a small rotating particle and a polarizable surface produces the friction torque on the particle, changes the attraction force (van -der -Waals force) and the rate of heat exchange in this system. In this paper we consider the case where the rotation axis is parallel to the surface. We present general theoretical basis allowing to obtain characteristics of the interaction at an arbitrary orientation of the rotation axis. In comparison to the case where the rotation axis is perpendicular to the surface (arXiv: 1208.2603), the obtained integral expressions for the friction torque, interaction energy and heating rate have different numerical coefficients. Numerical estimations are given in the case Au (particle)- Au(surface) and SiC (particle)-SiC (surface).
