Contribution

It introduces a comprehensive relativistic framework for fluctuation-electromagnetic interactions of small particles in background radiation, extending previous models.

Findings

Derived general relativistic relations for heating rate and tangential force.

Compared relativistic results with nonrelativistic and other relativistic models.

Provided insights into particle-radiation interactions at relativistic speeds.

Abstract

A relativistic theory of fluctuation -electromagnetic interaction of a small polarizable particle moving with respect to the equilibrium background radiation is reviewed. It is assumed that the particle radius is smaller then characteristic wave length of the background radiation. General relativistic relations for the particle heating rate and tangential force are obtained and compared with nonrelativistic and relativistic expressions of other authors.
