Abstract

We have calculated the intensity of electromagnetic radiation from particles rotating in close vicinity to a transparent dielectric plate. The radiation is a result of quantum and thermal friction occurring during particle rotation, while the driving factor of radiation is a decrease in the kinetic energy of particle. The characteristic frequency of radiation is determined by the angular velocity and the temperature of the plate and surrounding vacuum background. These results are challenging for experimental verification in future.
