14 Jan 2008 | Abstract: | We consider the cosmological evolution in a recently suggested new model of
quantum initial conditions for the Universe. The effective Friedmann equation
incorporates the effect of the conformal anomaly of quantum fields and,
interestingly, shows that their vacuum Casimir energy is completely screened
and does not gravitate. The cosmological evolution also features a new
mechanism for a cosmological acceleration stage. This stage is followed by a
big boost singularity -- a rapid growth up to infinity of the scale factor
acceleration parameter. We also briefly discuss the relation between our model,
the AdS/CFT correspondence and RS and DGP braneworlds. | Source: | arXiv, 0801.2063 | Services: | Forum | Review | PDF | Favorites |
