Constraining dark energy [PDF]
Ulf H. DanielssonIn this paper we propose a mechanism that protects theories violating a holographic bound suggested in arXiv:1203.5467 from developing accelerated expansion. The mechanism builts on work on transplanckian physics, and a non-trivial choice of vacuum states. If correct, it lends further support for detectable signatures in the CMBR signalling new physics.View original: http://arxiv.org/abs/1204.3311
