Low energy effective string cosmology.
We give the general analytic solutions derived from the low energy string effective action for four dimensional Friedmann-Robertson-Walker models with dilaton and antisymmetric tensor field, considering both long and short wavelength modes of the H-field. The presence of a homogeneous H-field significantly modifies the evolution of the scale factor and dilaton. In particular it places a lower b...
متن کاملLow-energy Graceful Exit in Anisotropic String Cosmology Backgrounds
We discuss the possibility of a smooth transition from the pre-to the post-big bang regime, in the context of the lowest-order string eeective action (without higher-derivative corrections), taking into account with a phenomenological model of source the repulsive gravitational eeects due to the back-reaction of the quantum uctuations outside the horizon. We determine a set of necessary conditi...
متن کاملIs There Chaos in Low-Energy String Cosmology?
Bianchi type IX, ’Mixmaster’ universes are investigated in low-energyeffective-action string cosmology. We show that, unlike in general relativity, there is no chaos in these string cosmologies for the case of the tree-level action. The characteristic Mixmaster evolution through a series of Kasner epochs is studied in detail. In the Einstein frame an infinite sequence of chaotic oscillations of...

متن کاملDark Energy in Perturbative String Cosmology
The apparent observation of dark energy poses problems for string theory. In de Sitter space, or in quintessence models, one cannot define a gauge-invariant S-matrix. We argue that eternal quintessence does not arise in weakly coupled string theory, but point out that it is difficult to define an S-matrix even in the presence of perturbative potentials for the moduli. The solutions of the Fisch...
