Bound states due to an accelerated mirror

In this Brief Report we discuss an effect of accelerated mirrors which has remained hitherto unnoticed: the formation of a field condensate near its surface for massive fields. From the viewpoint of an observer attached to the mirror, this effect is rather natural because a gravitational field is felt there. The novelty here is that since the effect is not observer dependent even inertial observers will detect the formation of this condensate. We further show that this localization is in agreement with Bekenstein’s entropy bound.
