Does Unruh radiation accelerate the universe? A novel approach to dark energy
arXiv:astro-ph/0607531
Abstract
In braneworld scenario, the brane accelerates in the bulk, and hence it perceives a thermal bulk filled with Unruh radiation. We put forward that there may be an energy exchange between Unruh radiation in the bulk and the dark matter confined to the brane, which accelerates the universe.
