    "abstract": "The thermal radiance felt by a uniformly accelerated\ndetector/oscillator/atom--the Unruh effect-- is often mistaken to be some\nemitted radiation detectable by an observer/probe/sensor. Here we show by an\nexplicit calculation of the energy momentum tensor of a quantum scalar field\nthat, at least in 1+1 dimension, while a polarization cloud is found to exist\naround the particle trajectory, there is no emitted radiation from a uniformly\naccelerated oscillator in equilibrium conditions. Under nonequilibrium\nconditions which can prevail for non-uniformly accelerated trajectories or\nbefore the atom or oscillator reaches equilibrium, there is conceivably\nradiation emitted, but that is not what Unruh effect entails.",
