Classical and quantum solutions to anisotropic cosmological Bianchi type I model from a time-dependent toroidal compactification | | L. Toledo Sesma

12 Jan 2015 | | Abstract: | In this work we construct an effective four-dimensional model by
compactifying a ten-dimensional theory of gravity coupled with a real scalar
dilaton field on a time-dependent torus. This approach is applied to
anisotropic cosmological Bianchi type I model for which we study the classical
coupling of the anisotropic scale factors with the two real scalar moduli
produced by the compactification process. Under this approach, we present an
isotropization mechanism for the Bianchi I cosmological model through the
analysis of the ratio between the anisotropic parameters and the volume of the
Universe which in general keeps constant or runs into zero for late times.
Finally, we present some solutions to the corresponding Wheeler-DeWitt (WDW)
equation in the context of Standard Quantum Cosmology. | | Source: | arXiv, 1501.2779 | | Services: | Forum | Review | PDF | Favorites | |
