14 Nov 2017 | Abstract: | We show that massive particles created in a relativistically accelerated
reference frame, as predicted by the Unruh effect, can only be found in a tiny
layer above the event horizon, whose thickness corresponds to a single Compton
wavelength. This is beyond the reach of any detector and suggests that the
Unruh effect may not ever be directly observed for massive fields. The case of
massless particles is also examined, for which qualitatively different
behaviour is observed in a low-acceleration regime, suggesting that an
observation of the Unruh effect for massless particles is more promising. | Source: | arXiv, 1711.5179 | Services: | Forum | Review | PDF | Favorites |
