A Heat Shield for de Sitter space | Paul Davies

2 Nov 2020 | Abstract: | We investigate a quantum vacuum state for $1 + 1$ dimensional de Sitter
space, corresponding to a region within a perfectly reflecting symmetric box of
fixed physical size. We find that a particle detector inside the box registers
zero response, implying that the walls of the box screen out the thermal
effects of the de Sitter horizon. The box thus creates a ’quiescent oasis’ with
a temperature below the de Sitter horizon temperature, an unexpected feature
that opens the way to an analysis of heat and entropy exchange between the box
and the horizon in the context of the generalized second law of thermodynamics.
We also calculate the stress-energy-momentum tensor of the region within the
box, showing that the total energy in the box is less than the same volume of
de Sitter space in the presence of thermal fluctuations. | Source: | arXiv, 2011.01169 | Services: | Forum | Review | PDF | Favorites |
