摘要

We calculate the quantum heat generation, the interaction force, and the frictional torque for two rotating spherical nanoparticles with a radius R. In contrast to the static case, when there is an upper limit in the radiative heat transfer between the particles, for two rotating nanoparticles the quantum heat generation rate diverges when the angular velocity becomes equal to the poles in the photon emission rate. These poles arise for the separation d < d_0 = R[3/ε"(ω_0)]~(1/3) [where ε"(ω_0) is the imaginary part of the dielectric function for the particle material at the surface phonon or plasmon polariton frequency ω_0] due to the anomalous Doppler effect and the mutual polarization of the particles and they exist even for the particles with losses. Similar singularities exist also for the interaction force and the frictional torque. The obtained results can be important for biomedical applications.
