  The fluctuations of the electromagnetic field are at the origin of the
near-field radiative heat transfer between nanostructures, as well as the
Casimir forces and torques that they exert on each other. Here, working within
the formalism of fluctuational electrodynamics, we investigate the simultaneous
transfer of energy and angular momentum in a pair of rotating nanostructures.
We demonstrate that, due to the rotation of the nanostructures, the radiative
heat transfer between them can be increased, decreased, or even reversed with
respect to the transfer that occurs in absence of rotation, which is solely
determined by the difference in the temperature of the nanostructures. This
work unravels the unintuitive phenomena arising from the simultaneous transfer
of energy and angular momentum in pairs of rotating nanostructures.
