Recently Pieplow and Henkel (2013 New J. Phys. http://dx.doi.org/10.1088/1367-2630/15/2/023027 15 http://dx.doi.org/10.1088/1367-2630/15/2/023027 ) presented a new fully covariant theory of the Casimir friction force acting on small neutral particle moving parallel to flat surface. We compare results of this theory with results which follow from a fully relativistic theory of friction in plate–plate configurations in the limit when one plate is considered as sufficiently rarefied. We show that there is agreement between these theories.
