Accelerating Cosmologies from S-Branes
We point out that the recently proposed model of a flat 4-dimensional universe with accelerated expansion in string/M-theory is a special case of time-dependent solutions that the author found under the name of “S-branes.” We also show that similar accelerating models can be obtained from S-branes if the internal space is chosen to be hyperbolic or flat spaces. PACS numbers: 04.50.+h, 11.25.Yb,...
متن کاملAccelerating cosmologies from exponential potentials
It is learnt that exponential potentials of the form V ∼ exp(−2cφ/Mp) arising from the hyperbolic compactification of higher-dimensional theories are of interest for getting short periods of accelerated cosmological expansions. Using such a potential derived for the combined case of hyperbolic-flux compactification, we study a fourdimensional flat (or open) FRW cosmolgy and give analytic (and n...
متن کاملEternally accelerating cosmologies from S-brane
We construct an eternally inflating spacelike brane world model. This model is feasible only if the space dimension of the brane is three (SM2) or six (SM5) for M theory or four (SD3) for superstring theory. A time-dependent n-form field would supply a constant energy density and cause eternal expansion of the spacelike brane. On the other hand, the hyperbolic space perpendicular to the brane w...
متن کاملAccelerating cosmologies from M/String theory compactifications
We point out that the solution of (4 + n)-dimensional gravity coupled to the dilaton and an n-form field strength can give rise to a flat 4-dimensional universe (with a scale factor) of the type proposed recently under time dependent compactifications. The compact internal spaces could be hyperbolic, flat or spherical and the solution is identical to the space-like two brane or S2-brane. We sho...
متن کاملSp-brane accelerating cosmologies
We investigate time dependent solutions (S-brane solutions) for product manifolds consisting of factor spaces where only one of them is non-Ricci-flat. Our model contains minimally coupled free scalar field as a matter source. We discuss a possibility of generating late time acceleration of the Universe. The analysis is performed in conformally related Brans-Dicke and Einstein frames. Dynamical...
