Statistical sum in the CFT driven cosmology | | A.O.Barvinsky
; | | Date: |
9 Dec 2010 | | Abstract: | The path integration technique recently developed for the statistical sum of
the microcanonical ensemble in cosmology is applied to the calculation of the
one-loop preexponential factor in the cosmological model generated by a
conformal field theory (CFT) with a large number of quantum species -- the
model of initial conditions possibly related to the resolution of the
cosmological constant and landscape problems. The result is obtained for a
class of background cosmological instantons with one oscillation of the FRW
scale factor. The magnitude of the prefactor is analytically and numerically
estimated for fields of various spins conformally coupled to gravity. | | Source: | arXiv, 1012.1896 | | Services: | Forum | Review | PDF | Favorites | |
