Quantum Fluctuations in Open Pre-Big Bang Cosmology

We solve exactly the (linear-order) equations for tensor and scalar perturbations over the homogeneous, isotropic, open pre-big bang model recently discussed by several authors. We find that, in spite of claims to the contrary, vacuum quantum fluctuations, although parametrically amplified, remain n...

description We solve exactly the (linear-order) equations for tensor and scalar perturbations over the homogeneous, isotropic, open pre-big bang model recently discussed by several authors. We find that, in spite of claims to the contrary, vacuum quantum fluctuations, although parametrically amplified, remain negligible throughout the perturbative pre-big bang phase.
