  Quantizing the electromagnetic vacuum and medium fields of two nanoparticles,
we investigate the heat transfer between them. One of the particles has been
considered to rotate by angular velocity $ \omega_0 $. The effect of rotation
on the absorbed heat power by the rotating nanoparticle is discussed. The
results for angular velocities much smaller than the relaxation frequency $
\Gamma $ of the dielectrics are in agreement with the static nanoparticles,
however increasing the angular velocity $ \omega_0 $ in comparison to the
relaxation frequency of the dielectrics $ (\omega_0\geqslant \Gamma) $
generates two sidebands in the spectrum of the absorbed heat power. The
well-known near-field and far-field effects are studied and it is shown that
the sidebands peaks in far-field are considerable in comparison to the main
peak frequency of the spectrum.
