Stable compactification and gravitational excitons from extra dimensions
Günther, U.; Zhuk, A.
Abstract
We study inhomogeneous multidimensional cosmological models with a higher dimensional space-time manifold under dimensional reduction. Stability due to different types of effective potentials is analyzed for specific configurations of internal spaces. Necessary restrictions on the parameters of the models are found and masses of gravitational excitons (small inhomogeneous excitations of the scale factors of the internal spaces near minima of effective potentials) are calculated.
Keywords: string theory; moduli stabilization; scalar-tensor theory; higher dimensional gravity; dimensional reduction
