Query: Quantum radiation from a particle in an accelerated motion coupled to
  vacuum fluctuations   A particle in a uniformly accelerated motion exhibits Brownian random motions
around the classical trajectory due to the coupling to the field vacuum
fluctuations. Previous works show that the Brownian random motions satisfy the
energy equipartition relation. This thermal property is understood as the
consequence of the Unruh effect. In the present work, we investigate the
radiation from the thermal random motions of an accelerated particle coupled to
vacuum fluctuations. The energy flux of this radiation is negative of the order
smaller than the classical radiation by the factor a/m, where a is the
acceleration constant and m is the mass of a particle. The results could be
understood as a suppression of the classical radiation by the quantum effect.
